1968 - 1972 + 1983 Green Proof Sets in Original Government Packaging - 6 Sets in total

This set includes the 1968–1972 and 1983 U.S. Mint Proof Sets, all housed in their Original Government Packaging (OGP), widely recognized by collectors as the classic blue boxes. Each set features the coinage of its year, struck in proof quality with sharp details and mirror-like fields that emphasize the artistry of U.S. Mint designs.

Blue Box Proof Sets in OGP

The 1968–1972 issues represent the Mint’s return to proof coinage following the 1965–1967 Special Mint Sets. After 1972, the blue box Proof Sets were discontinued until 1983, when the Mint reintroduced them after a decade-long break. Collectors value these sets both for their history and their distinctive presentation in the iconic blue packaging.
