The unprecedented crossover underscores his personal efforts to combat “grade inflation.”
The 2014 National Baseball Hall of Fame Commemorative Half Dollar holds a unique place in U.S. Mint history as the country’s first concave coin.
Created to celebrate the 75th anniversary of the Baseball Hall of Fame, this coin features a curved design where the obverse (front) side is concave, resembling the shape of a baseball glove, while the reverse (back) side is convex, mimicking the curve of a baseball. This innovative shape not only highlights America’s national pastime but also showcases the U.S. Mint’s technical skill and creativity in coin design, creating a unique and fitting tribute to baseball.
