The US Mint did not produce any coins with a mintmark from 1965-1967. Silver was also removed from coins during this time, and proof sets and mint sets were not produced either. It wasn’t until 1968 that mintmarks, proof sets, and mint sets returned to normal. See why 1965 coins, 1966 coins, and 1967 coins are different, and what’s so unique about 1968 coins.

# Proof Sets

Typically, Proof Sets contain one example of the cent, nickel, dime, quarter, and half dollar produced in a given year -- in the finest quality. Proof coins are specially treated and struck twice in order to create an exceptional finish (a frosted, raised foreground and a shiny, mirror-like background). Proof coins have been made since as early as 1821 -- however, they have only been offered in sets since 1950. Proof versions of a few recent commemorative coins (like American Eagle bullion coins and 1999 Susan B. Anthony dollar coins) have been offered individually. Proof Sets are more expensive and more valuable than Mint Sets.
