The National Baseball Hall of Fame and the United States Mint has unveiled the first-ever curved commemorative coin to honor the 75th anniversary of the National Baseball Hall of Fame and Museum.

At a launch event on Capitol Hill, Hall of Famers Joe Morgan and Brooks Robinson joined Treasurer of the United States Rosie Rios, as well as Kirsten Gillibrand and Richard Hanna (NY), who co-sponsored the legislation that called for production of the coin.

The coin’s curved design is the first of its kind by the Mint. A baseball is depicted on the tails side. A baseball glove is illustrated on the heads side, which curves inward reflecting the natural shape of a baseball mitt.

The National Baseball Hall of Fame Commemorative Coin Act authorizes the United States Mint to mint and issue up to 50,000 $5 gold coins, 400,000 $1 silver coins, and 750,000 half-dollar clad coins in recognition and celebration of the National Baseball Hall of Fame and its 75th anniversary.
