This 2 piece set of gold foil $5 and $10 notes are struck from 100 milligrams of 24kt gold. These recreations use the same exact design as the actual $5 and $10 certificates! The $5: a 1899 U.S. Treasury Gold Certificate featuring Native American Chief Running Antelope (leader of the Hunkpapa Tribe of Lakota Native Americans) in full headdress. The $5 note was the largest denominations of these Indian Chief Notes and considered the most popular among collectors. The $10: a 1901 $10 Bison Note, the same that circulated the nation during the 100th anniversary of Lewis and Clark expedition. Features a Bison grazing in a great plain with red highlights on the note similar to its regular issue counterpart. This is considered the #1 most popular $10 note in currency today. This is however, NOT Black Diamond (the famous Bison for the Buffalo nickel), this note was created using a stuffed bison at the Smithsonian. A collecting fact not many know! These replica's are the first of their kind to use this new minting technology and each one of them shines!
