The United States Mint took a hiatus from mint set production during 1982 and 1983. This has proven to be a financial boon to those wise people who managed to hang onto uncirculated rolls of high-denomination 1982 and 1983 coinage. Because there were no official mint sets produced in 1982 and 1983 (however, the Philadelphia and Denver mints did sell souvenir sets in their gift shops; these souvenir sets contain one coin of each denomination struck at that mint), there are relatively few uncirculated examples of some 1982 and 1983 regular mint sets.

The mint did not produce U.S. Mint Sets in 1982 and 1983; however, during those years, “Souvenir Mints Sets” were made by various private companies, including the U.S. Mint itself. The sets that have the U.S. Mint Bronze Medals in them were produced at the U.S. Mint and sold as "Souvenir Sets” at the Philadelphia ~ Denver Mint Shops.
