proof coin or proof Meaning, Definition & Usage
Definitions
- a coin which has been specially struck, to produce the finest specimen of its type.
Usually such coins are double-struck from polished dies, and the raised features are sometimes frosted. They thus have sharper features and more mirror-like fields than production coins (i.e. those coins struck for circulation); they are considered by coin collectors as the most desirable specimens of each coin, and usually sell at a premium to their corresponding production coins.
