The U.S. Mint will break a longstanding tradition, and it’s all in the name of America’s pastime. In 2014, the Mint will produce curved commemorative coins that are baseball themed.
Following is the description of the design:
The common obverse (heads) design depicts a glove that, combined with the baseball design featured on the reverse, exemplifies the most basic elements of our national pastime or a simple game of catch in the backyard or at the local sandlot. The glove design also highlights the unique concavity of the coin.
According to MLB.com, there have been concave coins prior to this set; however, these will be the first ever stamped at the Mint.
The coins celebrate the 75th anniversary of the National Baseball Hall of Fame. They will go on sale in early 2014.
