The first curved coins from the United States Mint are set to go on sale on March 27.
The limited edition coins, which are part of the 2014 National Baseball Hall of Fame Commemorative Coin Program, include a $5 US gold coin, a $1 silver coin and a half-dollar clad coin.
The concave design, the creation of artist Cassie McFarland, features a baseball glove on one side and a ball on the other. It was designed in recognition of the National Baseball Hall of Fame, which celebrates its 75th anniversary this year.
US commemorative coins celebrate and honour American people, places, events, and institutions and help to raise money for important and charitable causes. They are legal tender, but are not minted for general circulation and each design is only available for a limited time.
"These coins commemorate important aspects of American history and culture," said Richard A. Peterson, United States Mint Deputy Director. "This is a great way to connect with America's pastime through this 2014 National Baseball Hall of Fame Commemorative Coin."
The coins will go on sale starting at noon ET on March 27 at www.usmint.gov.
