The U.S. Mint Makes Its First-Ever Domed Coin

Later this month, the U.S. Mint will release a coin unlike any it’s ever made. Instead of being flat, it is shaped something like a bowl, with a convex surface that calls to mind a ball. A baseball, to be precise.

The design, commemorating the 75th anniversary of the National Baseball Hall of Fame, bears the image of a baseball on one side. The obverse side, as it’s officially known, shows a baseball glove, gently curving inward. It’s a clever marriage of form and content, with the convex and concave sides lending the ball and the mitt a measure of three-dimensional realism. It’s also about as radical as coinage gets, and required an unprecedented effort by our nation’s money makers.

“This was like a moonshot for us,” says Stephen C. Antonucci, manager of digital development for the U.S. Mint in Philadelphia. “It stretched the bounds of everything we knew about coin development.” Via How the U.S. Mint Made Its First-Ever Domed Coin
