This is a natural nugget of copper from the glacial drifts in Michigan. As a glacier moved across the copper district during the Ice Age, it scraped this copper from the earth and then deposited it as a nugget. This 3.2-ounce nugget has been polished on one side to show off its penny-bright luster, which contrasts beautifully with the antique patina in the recesses. The other side has been left natural. 5.2 x 3.9 x 1.3 cm
