½ Dollar (Huguenot-Walloon Tercentenary)

The Huguenot-Walloon Half Dollar: a coin for a 1624 voyage, picturing two men who died before it sailed

In 1924 the United States struck a silver half dollar to mark a voyage from 1624 — and put two famous faces on it who had both been dead for forty years when that ship set sail. That mismatch, and the fact that churches were selling the coin, made it one of the more argued-over commemoratives of its era.
