Double Eagle 

This term refers to the US $20.00 Gold piece that was minted up until 1933 when POTUS FDR forced the American people to turn in their Gold so he could increase the value of Gold and thereby reduce the value of the American Dollar. Nice guy!  While I hate to have to admit it, FDR seems to have been a Mason but I have no Lawful Masonic Information to prove this statement.
