The regular dies trial piece, in copper, for the 1860 Indian cent. These are believed to be true die trials as opposed to being deliberately struck for sale to collectors as happened in later years.
Pollock lists only the rounded bust truncation variety. Rick Snow, however, notes that examples exist of both the pointed and rounded bust varieties. The illustrated piece is the pointed variety and is of an actual example and appears to be from business strike dies.
At least 3 are believed to exist, 2 of which are from a pointed bust truncation die and 1 which is from a rounded bust truncation die. An example listed in the Smithsonian's inventory appears to be a regular issue copper-nickel cent and not a copper die trial.
