Key Coin/Key Date
The major, or most important, coin in a particular series. The "key" coin is usually the lowest-mintage coin and/or the most expensive coin in a particular set. The 1916-D dime, for instance, is usually considered the key coin of the Mercury dime series. It is the lowest mintage coin of the set and the most expensive (in most grades). The 1919-D dime is the "condition rarity key" of the Mercury dime series, as it is the most expensive coin in top condition.
