The grading scale adopted by Classical Coin Grading is based on the Sheldon scale, international measure for the conservation states of coins around the world.
The Sheldon scale is applied to ancient and modern coins considering the peculiarities of the reference issues. After classifying and assessing the authenticity of the coins, Classical Coin Grading assigns the coin a code and a number that correspond to a specific conservation status.
With regard to the application of the reference judgments, a single distinction is made associated with two types of coins: ancient coins and modern coins. Given the dating and the technical characteristics that distinguish them, ancient coins are valued according to a special process that provides, in addition to the normal assignment of the score, a bonus/malus rating based on centering, patina, flan characteristics, style, minting imprint and glance.
|MS (60 to 70)||Mint state - Uncirculated||The coin has no signs of circulation, it may at most have limited signs of contact with other coins due to the production process.|
|AU (50, 53, 55, 58)||Almost uncirculated||The coin has circulated very little and all the reliefs are intact.|
|XF (40, 45)||Extremely Fine||The coin has circulated and the major reliefs show signs of wear, while the coin is perfectly readable.|
|VF (20, 25, 30, 35)||Very Fine||The coin is worn and some parts are not legible|
|F, VG, G, Fair, Poor (1, 2, 5, 10, 15)||Fine, Very Good, Fair, Poor||The coin has heavily circulated and most of the reliefs have disappeared|
Modern coins are minted using high-precision machines in an industrial process. For modern coins, a distinction is made between the following types of issues.
Ancient coins are minted using artisanal techniques. In addition to an evaluation expressed according to the Sheldon scale, we have introduced 7 parameters to better specify the degree of conservation of this type of coin. These parameters appear in the coin's online tab as bar indicators.
