1860 Copper $20 Clark Gruber K-4a Die Trial NGC UNC Details Private Countermark
The regular issue Clark, Gruber & Co. gold twenty dollar piece exhibited a volcanic representation of Pikes Peak, but the copper trial instead has a stylized triangular rendition. The date side die, featuring an eagle similar to that on the Federal Liberty ten dollar, struck both the 1860 copper trial and regular gold issue. This glossy chocolate-brown and gunmetal-blue example is richly defined and shows a small 5 counterstamp below the eagle's left (facing) claw. We think it adds character and allure about the Wild West!
