This 1920-P Lincoln Cent was broadstruck on an Argentina 10 centavos planchet weighing 3.1 grams. The U.S. Mint struck copper-nickel 10 centavos pieces for Argentina in 1920. One of the planchets passed through the upset mill, then found its way between Lincoln cent dies. The uncentered broadstrike is a second and probably unrelated mint error .

This 2000-P Sacagawea dollar error was struck on copper-nickel ring intended for a Ghana 100 Cedis. The 100 Cedis is a bimetallic coin with a brass center framed by a copper-nickel outer ring. The ring almost certainly came from the Royal Canadian Mint, mixed in with a shipment of Sacagawea planchets. During periods of peak demand, the RCM processed dollar planchets for the U.S. Mint. The diameter of the ring was close enough to the standards of a Sacagawea dollar to escape the Mint riddlers.
