In 1983 the U.S. Mint introduced the Prestige Proof Set from the San Francisco Mint. They are sets that included the 6 regular issue coins (the Cent through the Half Dollar) and then the special Commemorative coin(s) of that year.
This is the 1992 Prestige Proof Set. It Includes the 1992 Olympic Silver Dollar and Clad Half Dollar. The Silver Dollar is known as the Nolan Ryan Dollar because the image is the same as the 1991 Fleer Baseball card #401
The coins in the Prestige Proof set are presented in a deluxe plastic lens and displayed in a collector album, with a display box and a Certificate of Authenticity (COA).
