1978 U.S. Proof Set in Original Government Packaging
Description
Proof means that the coin was minted using polished dies, it can be
distinguished from normal circulation coins by its sharper rim and design. The
dies for making proof coins are treated with chemicals to make certain parts
of the coin’s design take on a frosted appearance with the polished fields
taking on a mirror finish. Proof coins are double struck at twice the pressure
of normal circulation coins, to ensure the coins are struck fully. Proof coins
are manufactured as specimen coins for collectors and museums.
