The Science of Coin Grading: How to Assess and Value Your Collection
A coin’s physical condition is evaluated during the coin grading process. This evaluation takes into account a variety of characteristics, including wear, lustre, colour, and any flaws that may be present. The Sheldon Scale, which has a range of 1 to 70, is the grading scale that is received the most widespread acceptance. While a coin with a grade of 1 is in the worst possible condition, a coin with a grade of 70 is in mint condition.
Important Criteria for Grading
1. Wear and Tear: The degree of wear is the most important contributing factor. The high points of coins that have been circulated show variable degrees of wear, but coins that are still in their mint state show no signs of wear.
2. “Lustre” is a term that describes the sheen that was produced by the coin itself during the first minting process. It is possible for the lustre of a coin to disappear over time as a result of handling or environmental causes.
