1956 Proof Set~In OGP

The 1956 Proof Set includes proof versions of the circulating coins of that year—cent, nickel, dime, quarter, and half dollar. These coins are specially struck with polished dies to create a sharp, detailed finish. The 1956 set is notable as it was the first year that the U.S. Mint offered proof sets in flat-pack packaging, departing from the traditional box design.
