Coin of exceptionally high quality, where quality is determined not just by wear of the coin in circulation but also by the wear and artistic quality of the dies from which it was minted. These factors are crucial for ancient coinage where variability was higher than in modern mints. See also Grade.
The condition of a coin or amount of wear that a coin has received. Common grade terms used in the UK are Fine, Very Fine, Extremely Fine and Uncirculated. These grades can be split into divisions, Nearly and About are sub-grades and Good is an over grade e.g. “About Very Fine” is just below “Very Fine” and “Good Very Fine” is just above “Very Fine”.
A coin with the raised design high above the field. Coins struck in high relief often have problems with details not coming up sharp enough and dies having a shorter than usual lifespan. If the design is higher than the rim, the coin may not be stackable, and the highest points of the design will wear away very quickly.
