1964 US Proof Set - OGP

The Proof Set contains the highest quality coins struck each year by the United States Mint. This is accomplished by using a specialized minting process in which they are double struck, leaving the coins with an absolutely razor sharp image and a deep mirror-like field. The United States Proof Sets, much like their Mint Set brethren, consist of one proof-version of each coin struck in each denomination released into circulation during that year.
