1 Dollar (Dolley Madison)

The 1999 Dolley Madison Silver Dollar

In 1999 the U.S. Mint did two things it had never done before on a single coin: it put a First Lady's face on American money, and it let the jeweler Tiffany & Co. design it. Look closely and you can find the proof — the firm's "T&Co." mark is struck right into the coin.
