1933 double eagle
The 1933 US 20 dollar gold coin (shows the double eagle) exists only in a very small number of specimen. Initially, it was created in 450.000 exemplars, but never officially circulated, because of the end of the use of gold dollars in 1933. US president Franklin D. Roosevelt set into power legislation to putting an end to the 1930s general bank crisis with the Emergency Bank Relief Act (March 1933) and the Gold Reserve Act (January 1934). The circulation and private possession of US gold was ruled out (with exemption for collector coins). The never officially made public 1933 gold coins were melted down in late 1934. Only two coins in the US National Numismatic Collection and a small number of others, which found their way illegally into the hands of collectors, survived.
