2. Included are 2 Philadelphia and 2 Denver Mint sets. These sets were issued from 1947-1958 and were housed in cardboard cut-out holders showing each denomination produced that year from each of the mints. There was a paper covering to protect the coins and the boards. The paper was glued down to one side of the board while the other side was simply covered loosely by the paper, thus allowing easy viewing of the coins. These paper-covered boards were then placed into an envelope and this envelope was placed into a secondary mailing envelope. The sets were then mailed to the happy collector. Since the paper was glued down on one side, the mint issued two of each denomination to allow both the obverse and reverse to be viewed. Thus the name “Double Mint Sets”!
