1908 US Indian Head Gold Five Dollar Half Eagle in 14k Gold Bezel 

This lovely American coin was the first to have an engraved relief rather than a raised relief design. President Theodore Roosevelt,  interested in every aspect of the government, turned his attention to the US Mint during the first decade of the 20th Century and commissioned this unusual sunken design after a friend mentioned seeing similar incuse relief designs on Egyptian art in a museum. 

Roosevelt commissioned Bela-Lyon Pratt to design the coin and it entered circulation  in 1908.
