Proofs and Proof sets
Proofs are specially manufactured coins using polished dies and selected planchets, to give the coin a mirror effect. The dies for making current U.S. proofs are often treated with chemicals to make particular parts of the design have a frosted appearance. Generally, proof coins are double struck. Starting in 1936, the U.S. Mint began producing proof sets. These sets are the highest quality issues of coins. The term proof is a reference to a type of coin and not the grade of the coin. The proof issues are struck for collectors and not for circulation.
