Experimental Surface

In 1907, the United States Mint started to experiment with the surfaces of U.S. gold coins in the denominations of $2 1/2, $5, $10 and $20. These were finished in a variety of surfaces including matte, roman and satin. The unique $20 1907 Matte Proof 64 gold piece certified by NGC is a historic striking of the only matte $20 for 1907.
