5 Dollars (San Francisco Old Mint Centennial)

The San Francisco Old Mint $5 Gold — a coin for the building that wouldn't burn

When the 1906 earthquake and fire leveled San Francisco, the city's banks burned to the ground — all but one. The San Francisco Mint stood through the flames with the nation's gold inside it, then opened its doors as the only bank in a ruined city. A century later, the U.S. Mint struck this $5 gold half eagle in its honor.
