The coin you can't lay flat
Pick almost any coin out of your pocket and it lies flat on a table. This one rocks.
The 2020 Basketball Hall of Fame silver dollar is curved — pressed into a shallow bowl. The front (the obverse — the "heads" side) caves inward, concave like a satellite dish. The back (the reverse) pushes outward into a dome. The Mint did this so the coin would echo the game it celebrates: the curve of a backboard, the arc of a ball in flight, the round mouth of a net seen from below.
It honored a milestone. The Naismith Memorial Basketball Hall of Fame in Springfield, Massachusetts — the city where James Naismith nailed up a peach basket and invented the game in 1891 — turned 60 in 2020. Congress marked the anniversary with a three-coin set: a small clad half dollar, this silver dollar, and a $5 gold piece. All three share the same dished shape.
The law behind it, the Naismith Memorial Basketball Hall of Fame Commemorative Coin Act, was signed on December 21, 2018 (Public Law 115-343). And as a U.S. commemorative, the coin pays its own way forward: a fixed surcharge — $10 on every silver dollar sold — goes straight to the Hall of Fame to fund its endowment and education programs. Buyers don't just collect a coin; they bankroll the museum.
