Assessment of the safety of ancient coins. Classification of coin condition
Classification of the condition (quality) of coins.
РRF, Proof- Coins of the highest collectible quality, issued specifically for collectors. They are made with polished stamps on a polished mug. Basic features These coins have a mirror field without any visible defects and a matte design. Proof coins that have received any damage as a result of handling are assessed in terms of condition as normal coins.Proof-like- the same as Proof, but for coins made of base metals (Currently, the Proof category provides for minting only in precious metals). bUNC, Brilliant uncirculated - improved quality. Same as Proof, but the image is not matted and the field is not always mirrored.
UNC- Very good condition. Coins that have a matte metallic sheen, are minted with unworn dies and have not been in circulation. Under a 2x magnification magnifying glass, stamping defects, scratches, nicks and other damage are invisible. Highest category condition for most coins.
XF or EF - excellent preservation of the coin. The coin was minted with unworn dies, has light abrasions visible to the naked eye in the highest areas of the relief, and small scratches that are formed as a result of coins hitting each other at the mint. The contours of the drawings are contrasting, all the smallest details of the relief are preserved, the embossed shine is completely preserved, there is no loss of presentation.
VF- very good preservation. Coins that have been in circulation for a long time and have noticeable signs of wear on the protruding areas of the design, minor scratches and nicks. General state The coins are in good condition, the contours of the relief are clear, the minted shine has been lost. Marketable condition partially lost.
F- good preservation. Coins with traces of being in circulation for a long time, with abrasions on the entire surface, traces of corrosion and cleaning. Small details are difficult to discern, the contours of the relief have lost their sharpness. This category also includes new coins that have minor minting defects.
VG- satisfactory preservation. Coins with significant abrasions on the entire surface, damaged in the form of deep scratches, notches and shells. Small details of the design, inscription and date of issue are difficult to distinguish or not distinguishable at all. This category also includes new coins with a significant mintage defect.
G- defective coins that have very serious damage, such as deformation of the disc, holes, very deep scratches, notches, cavities, severe wear, in which it is very difficult or impossible to determine the denomination and date of issue of the coin.
Assessing the condition of coins consists mainly of determining the degree of wear. The more significantly a coin is erased (worn out), the fewer elements of its design are distinguishable, the worse its condition (or the lower the degree of preservation).
In accordance with generally accepted international standards for assessing condition, used today by most numismatists, the following main gradations of the condition of coins (or the degree of their preservation) are distinguished:
Uncirculated (excellent condition).
In this condition, the coin should not show any signs of wear, and all its design details are usually clearly visible. Coins in this condition often have their original “chased” shine throughout their entire surface area. In this case, the presence of minor traces from storing coins in bags in the form of small nicks or scratches and some other defects is acceptable. Specialists on the Sheldon scale, depending on the presence and significance of these deficiencies, distinguish eleven small gradations of this state from MS 60 to MS 70. The term MS (short for “mint state”), used by specialists on the Sheldon scale, is synonymous with the concept Uncirculated.Sometimes, to determine the condition of coins that have minimal, that is, barely noticeable abrasion, the term is used
About Uncirculated (almost excellent condition - abbr. AU)
. According to the Sheldon system, as a rule, four gradations of the About Uncirculated state are distinguished: AU 50, AU 53, AU 55 and AU 58.Extremely Fine (excellent condition).
Coins in Extremely Fine (abbr. XF) condition have very slight wear on the most prominent small elements of the design. Typically, at least 90 - 95% of small details are clearly visible on such coins. Experts according to the Sheldon system divide coins in this condition into two gradations: XF 40 and XF 45.Very Fine (very good condition).
In Very Fine (abbr. VF) condition, coins already have very noticeable abrasions and somewhat smoothed out details of the design (as a rule, only about 75% of the details of the design are clearly visible). According to the Sheldon scale, coins of such preservation are divided into the following categories: VF 20, VF 25, VF 30, VF 35.Fine (good condition).
The Fine condition (abbr. F) is characterized by even more pronounced abrasion of the surfaces due to the long period of time the coin has been in circulation. Typically, approximately 50% of the coin's original design details are visible. Specialists in the Sheldon system distinguish two states: F 12 and F 15.Very Good (satisfactory condition).
Significant wear throughout the coin. In Very Good (abbr. VG) condition, as a rule, only about 25% of the original elements of the coin’s design are preserved. According to the Sheldon scale, states VG 8 and VG 10 are distinguished.Good (weak state - abbr. G).
Very intense wear on the coin. Usually, predominantly the largest details of the coin’s design are visible. According to the Sheldon system, there are two degrees of this condition - G 4 and G 6.Summarizing the above about the main degrees of safety of coins according to international standards and the terminology of the Sheldon 70-point system, the following table can be compiled:
International system | Dr. Sheldon scale | Russian terminology |
PF (proof) | PF 1-70 | polished |

When coins are sold at a numismatic auction, they must be assessed by professionals. In addition to the value due to its rarity, the safety of the coins is also important, the decoding of which should be known to every numismatist in order to know how to determine the price.
Professional dealers and collectors primarily pay attention to such criteria as the condition, type and degree of preservation of the coin. All this constitutes the concept of its collectible or numismatic value. It is especially important to correctly determine the value of ancient coins that have been kept in someone’s collection for a long time, perhaps incorrectly, and were also in free circulation. Often these coins have a high degree of damage or wear.
Even a very common coin can be equated to very rare if it has a high, almost perfect degree of preservation. Small differences, including those that may not be noticeable to the naked eye additional equipment, often determine its cost.
Designations of the degree of preservation of coins according to classification
It's a matter that requires hard work and experience. And although there are general criteria, often the opinions of experts can differ greatly due to the huge number of factors influencing such an assessment.
Classification of coins by degree of preservation
The condition of each coin can be determined according to standards that apply throughout the world, and which guide numismatists and appraisers.
You can often see that where the quality of the coin should be written, there is a mark such as proof. This gives rise to a lot of controversy about what it really is. So, the proof has nothing to do with the condition of the coins. Proof is a method of minting a coin. When a new stamp is developed and approved, proof coins are first made.
If a coin has abrasions or damage, it is graded on a general scale. The classification of coin condition is as follows:
1) Uncirculated. Coins that are in perfect condition. In this case, there should be no abrasions, chips or deep scratches. There must be a minted shine, and the design of the coin must be perfectly preserved. The name is translated from English as “did not circulate” and means that the coin was handed over to collectors immediately after production or for storage; it was not in circulation.
This gradation has its own subtypes, it is called MS or mint state - there are 11 of them from MS 60 to 70.
2) About Uncirculated. This means that the coin is not of Uncirculated quality. AU has its own subtypes, and they are designated (AU 50, 53, 55 and 58).
3) There is also the highest degree of preservation, but it is not always used - Brilliant uncirculated (BU). These coins have never been in circulation and have no defects at all.
4) Extremely Fine. In this way they denote coins that have been in circulation for some time, but not for long. Small abrasions on the relief parts of the coin are allowed, as well as at least 90% of the legibility of the design. This type is designated as XF and has subtypes according to the Sheldon system XF 40 and XF 45.
5) Very Fine. This grade means "very good", the design on the coin should be 75% distinguishable (details), and the coins themselves may have significant abrasions, scratches and smoothing of the relief. This degree has 4 subtypes 20, 25, 30 and 35, and is designated as VF.
6) Fine. The coins are in good condition. Small details of the design should be on half the surface of the coin. Chips, abrasions and scratches can be any, but general details the images on the coin are viewed. The degree of gradation is designated as F, and according to the Sheldon scale it has two subtypes - 12 and 15.
7) Very Good. The penultimate level of the degree of preservation. Coins that have been graded according to this gradation have been preserved satisfactorily. The design on the coin is significantly damaged, only 20-30% can be seen, it has two subtypes - 8 and 10, designation - VG.
8) Good. The coin is in poor condition. The damage is very severe, only large details of the pattern can be seen, two subtypes are distinguished - 4 and 6, designated by the letter G.

Other disadvantages of coins
May have dark spots, be completely or slightly darkened, or have a rainbow color. This occurs due to the oxidation of silver. Darkened silver is formed when it interacts with hydrogen sulfide in the air. Often this color is valued more expensive by many collectors than pure silver. If the coin has been exposed to different substances, it may have a rainbow color. The natural origin of this color increases the value of the coin.
Absolutely - usually this characteristic is given to a coin that has been cleaned. The disadvantage is that any signs of authenticity in this case are completely absent. Usually, coins are cleaned not from patina or a uniform layer of oxides, but from harmful or unsightly stains. Sometimes part of the coin is left uncleaned so that its condition can be seen to assess authenticity.
Often the coin has traces of physical or chemical exposure. Sometimes some of these imperfections can be removed by cleaning, but remember that there is also a layer on the coin that forms over time and protects the metal from corrosion - patina. When cleaning, it is very important that the patina remains, as this can not only compromise the integrity of the main part of the coin, but also greatly reduce its value. Especially on copper and bronze coins, a beautiful patina can increase the value of the coin significantly. In catalogs, such characteristics of the condition of coins are most often found.
The patina may have several different colors, it depends on its origin and use. The following patina colors are distinguished:
- Green, the most common; it can be smooth and dense.
- Olive is a subspecies of green.
- Black patina is also considered a subspecies of green and looks very good.
- Red patina. This patina covers the coin unevenly, but in spots. It is classified this way if it covers a large area.
- Blue patina. This color is very rare; perhaps the coin lay in the ground for some time, and the composition of the soil gave it this shade.
- Earthy. Coins with such a patina are found in the provinces of the Roman Empire. Often combined with earthen deposits, similar to the effect of the patina being rubbed off from the top points of a coin.
Types of patina:
- Contrasting surface. Patina is not present on the entire surface of the coin, but at the highest points of the relief; it has wear.
- Dense patina. This surface of the coin is highly valued, but if the layer is too thick, some details of the design may not be visible.
- Chapped. Patina that may have chips or wear around the edges. It is not rated very highly, since through such chips the process of damage to the metal can begin.
- Patina with spots. Often looks worse than a coin with no patina at all. Such coins are cleaned so that they are then covered with a secondary patina.
- Secondary patina. Once a coin is cleaned or otherwise stripped of its patina, it will re-form if stored properly. It is also called “chocolate” because it has Brown color. Instances with such a patina have a beautiful appearance.
Coins that were originally coated with silver may lose it during circulation. Usually it looks sloppy and unsightly, so it must be tinted with sulfur compounds, which gives a black color.
If the coin has not been stored correctly and does not have a preserved patina, it may have a porous structure. Such coins are often found in rivers and are the result of exposure to active substances. There were coins in the Roman provinces that were originally minted in this condition. The porous surface may only be present on some part of the coin. This is referred to as a "partially pitted surface".
The term "rough and mottled surface" refers to mottled surfaces that are uneven and whose appearance is considered deteriorated. This result can be achieved, among other things, by improper cleaning.
Pitted with caverns refers to a surface, most of which is affected by corrosion. Found on coins over a thousand years old made of brass.
A machined coin is a coin whose surface bears marks from sharp tools so strong that it has an ugly appearance.
Unnaturally shiny - if the coin has lost a significant part of its details during the polishing process. It is possible that such a coin was restored, but some details of the design were replaced.
False restoration, low quality fake:
- Cracked coin. The presence of any cracks on a coin is very dangerous, it can seriously damage the coin itself and cause corrosion.
- Broken edge. This is typical for most coins from the period of antiquity. But in addition, this can also happen due to improper cleaning and operation. Such breaking off is also typical for coins that were minted on a blank with a crack.
- Scratched surface. A coin that was in circulation. If there are not too many scratches, then they are invisible, but this happens when it is not made of a soft alloy.
- Test strike. Certain traces of filling quality control inner surface metal coins.
- Trimmed coin. It was often a practice in ancient Rome to trim the thin flange of coins made of precious metals. It was illegal, but common nonetheless. Such a coin is valued much lower.
- Former jewelry. Ancient coins that were used as jewelry have this characteristic. They were often framed with precious metals and show signs of this, such as protrusions or marks.
The condition of a coin is a very important characteristic of it. Therefore, coins in a collection must be stored correctly. It is advisable that they have special packaging that protects against harmful effects. You must handle the coin with special care, always handle it only by the edge and with gloves, otherwise it will lose its value.
To clearly and accurately assess the condition of the coin, a special classification scale is used, which describes in detail the characteristics of each gradation. This classification is used by numismatists all over the world, and advertisements for the sale of coins must indicate their objective condition.
Polished state of preservation of the coin - PF
The polished state is the highest degree of preservation of a coin, which is ensured by certain measures applied immediately after its production. These are typically specially crafted collectible coins that are minted by hand and then placed directly into packaging. These coins are characterized by:
- coin mugs polished to a mirror shine, including the edge part;
- etched parts of the design on stamps to obtain a specific matte finish of the convex parts of the image;
- polished stamp field for more expressive and clean coinage;
- minting by hand in several strokes, due to which the stamp recesses are completely filled with metal, which ensures excellent elaboration of the smallest details of the design;
- placing coins in transparent plastic packaging to protect them from contact with fingers and the appearance of stains or micro-scratches.
This is how collectible coins are made today, but most of these rules were followed in the past, including Tsarist Russia, in the manufacture of collectible or donative (gift) coins.
International designations for polished coins:
- in English classification - Proof (PF)
- in German - Polierte Platte (PP) or spiegelglanz
- in French - Flan Bruni (FB)
- in American according to Dr. V. Sheldon - PF1-PF70
- in Scandinavian countries - M, polerad
Excellent state of preservation with mirror shine - PL
This category of coin quality was introduced into the classification relatively recently. It refers to coins that were struck under normal mass production conditions, but from highly polished blanks and using quality dies. As a rule, these are the first few hundred copies produced with new dies, or a random combination of circumstances that results in better-than-usual examples being produced. These coins are distinguished from the polished state by the lack of edge polishing, flaws in the polishing of the field and an insufficiently matted design. Nevertheless, they are very popular among collectors and are valued quite highly.
International designations for excellent condition with a mirror finish:
- in English classification - Prooflike (PL)
- in German - stempelfrich
- in French - presque poli
- in American according to Dr. V. Sheldon - MS with Prooflike addition, for example, MS67(PL)
- in Scandinavian countries - 0-M,polerad 0
Excellent state of preservation of the coin - UNC
These are coins that have not been in circulation and have little or no damage. The smallest scratches or burrs visible only to the naked eye are acceptable on the surface, which are formed by mutual friction of coins poured into bags and transported in these bags inside the mint. Distinctive feature UNC coins have a fresh shine of polished metal, which is called a “chandelier”. They say about such coins: they are practically untouched. Among numismatists they are called “uncirculated” or “anz” for short.
International designations for excellent condition:
- in the English classification - perfect uncirculated, as well as simply uncirculated (UNC)
- in German - erstabschlag (EA), stempelglanz (STGL, ST)
- in French - fleur de coin (FDC)
- in American according to Dr. V. Sheldon - MS70, MS69, MS68, MS67, MS66, MS65, MS64, MS63, MS62, MS61, MS60
- in Scandinavian countries - 0
Near Excellent State of Conservation - XF-UNC
Coins in almost excellent condition were in circulation for a very short time. They have lost the distinct chandelier, but remnants of shine are still present. In addition to technological damage characteristic of UNC, there may be minor scratches received in monetary circulation. They can be designated among CIS numismatists as unc-, xf+ or xf/unc.
International designations for near excellent condition:
- in the English classification - choice almost uncirculated, as well as almost uncirculated, choice about uncirculated, about uncirculated (XF-UNC)
- in German - bankfrisch (BF), unzirkuliert (UNZ)
- in French - fleur de coin (FDC), superbe (SUP)
- in American according to Dr. V. Sheldon - AU58, AU55, AU53, AU50
- in Scandinavian countries - 0.01
Excellent state of preservation of the coin - XF
This is the name given to coins that have been in circulation for some time. This condition is characterized by the presence of visible small abrasions in the highest areas of the relief, however, the design is well preserved in all, even the smallest details. Scratches and nicks are only very small, almost indistinguishable without a magnifying glass. In some places, residual chandelier may remain in the recesses between the details of the design. Numismatists call such coins “ixfine” or “xf”.
International designations for excellent condition:
- in English classification - extremely fine (XF)
- in German - vorzueglich (VZ), vorzueglich erhalten (VZE)
- in French - superbe (SUP)
- in American according to Dr. V. Sheldon - XF45, XF40
- in Scandinavian countries - 01
Almost excellent state of preservation of the coin - VF-XF
Due to the rather long period of circulation, quite noticeable abrasions of the protruding areas have formed on the surface of the coin, however, the contours of the design remain clearly visible, and the smallest details are not damaged. There is no metallic sheen even in the recesses; the surface may have traces of minor technological damage. Among numismatists in the CIS, such coins are designated vf/xf, xf-, vf+.
International designations for almost excellent condition:
- in the English classification - choice extremely fine, about extremely fine (VF-XF)
- in German - vorzueglich (VZ), sehr schon (SS), sehr schoen erhalten
- in French - superbe (SUP), tres tres beau (TTB)
- in American according to Dr. V. Sheldon - VF35, VF30
- in Scandinavian countries - 01.1+
Very good state of preservation of the coin - VF
This characteristic applies to the coin, it is enough long time was in monetary circulation, as a result of which there are quite noticeable abrasions not only on the protruding parts, but also on the entire rest of the surface. Some small details are no longer visible or have been completely erased, the contours are blurred, and there are small scratches and nicks. CIS numismatists define this condition as vf.
- in the English classification - very fine, choice very fine (VF)
- in German - sehr schon (SS), sehr schoen erhalten
- in French - tres tres beau (TTB)
- in American according to Dr. V. Sheldon - VF25, VF20
- in Scandinavian countries - 1+
Good state of preservation of the coin - F
This coin was in active circulation for a long time, due to which the small details of the relief were practically erased, but the general outline of the design is clearly visible - outer contour coat of arms, silhouette of an imperial portrait, etc., with small strokes completely absent. However, the denomination and date of issue are clearly visible. There may be scratches and nicks on the surface that do not disturb the design. In good condition, coins are designated by numismatists with the letter f or “fine.”
International designations for very good condition:
- in English classification - fine (F)
- in German - schon (S), schoen erhalten
- in French - tres beau (TB)
- in American according to Dr. V. Sheldon - VF15, VF12
- in Scandinavian countries - 1
Satisfactory state of preservation of the coin - VG
This is the definition of a coin that has been in active and long-term circulation. The design is partially erased; only the largest elements of the obverse and reverse can be distinguished; the collar and small details are practically indistinguishable. The relief is almost at the same height as the field of the coin; the denomination and date of issue may also be partially erased. There may be abrasions or gouges on the surface caused by contact with hard objects. Domestic numismatists classify such specimens as “verigud” or vg.
International designations for satisfactory condition:
- in English classification - very good (VG)
- in German - gut erhalten (GE)
- in French - tres bien conservee (TBC)
- in American according to Dr. V. Sheldon - VG10, VG8
- in Scandinavian countries - 2
Weak state of preservation of the coin - G
On coins in a state of poor preservation, as a rule, practically no information has been preserved that would allow identifying the date of its minting and denomination. From the design of the obverse and reverse, as a rule, only a blurred outline remains; no details suitable for accurate classification can be made out. The value of a piece is determined mainly by the cost of the metal. Among numismatists, such coins are called “gud”, “g” or “scrap”.
International designations for weak state:
- in English classification -good (G), poor (PR)
- in German - gering erhalten
- in French - bien conservee (BC)
- in American according to Dr. V. Sheldon - G6, G4, G3, P1
- in Scandinavian countries - 3
