Proof Sets

Proof sets are small collections of coins, packaged by the mint, which include specially produced versions of coins struck in a given year. Proof coins are those whose planchets (the blank piece of metal upon which a coin is struck) are highly polished and struck multiple times so as to render a coin with magnificent quality in detail. Upon the completion of the minting process, proof coins possess beautiful mirror-like surfaces, magnificent detail and, in the case of proof coins from the past two or three decades, frosted (cameo) designs.
