Legendary Coins and Currency
This online exhibition from the Smithsonian's National Museum of American History is a great way to get an overview of the history and highlights of American coinage of all denominations. Based on flash animation, the photo close-ups and timeline navigation will dazzle you, if not educate you. "Legends" is the theme here, with sections on legendary gold coins, beautiful coins, first-of-their-kind coins, and numismatic aberrations. Well done and fun!
