Starting in 1936 in 1936 the US government initiated a program of marketing special "sets" of the year's coin issues in proof format. From 1936-1955 the coins were delivered in boxes with cellophane packaging. Most of these coins have since been removed to protect their surfaces from the damaging wrappers. Values for coins from 1955 are listed for sets in their intact holders, as issued from the Mint.
