This Web site, Legendary Coins and Currency, was created in conjunction with a gallery exhibition no longer on display at the Smithsonian Castle. This exhibition, which opened on December 8, 2005 and closed February 11, 2008, explored rare and historically significant artifacts from the National Numismatic Collection (NNC)—more than half of which had never been on view, or not for many years. Coins, bills, medals, and captivating oddities—such as pattern designs, fake coins, and homemade clam shell money from the Great Depression—were on display.
