This coin began as a normal 2000-P dime that somehow got mixed into the cent planchet bin and was struck the following year, in 2001, at the Philadelphia Mint as a Lincoln Cent. Commonly referred to as an "11-cent piece," these errors are very popular with collectors, but very scarce with the dates of both coins visible, and rather rare to find with two different dates. Roosevelt was mostly flattened out by Lincoln in the second strike. Similar on the reverse where the original dime designs are present but mostly struck out by the force of the Lincoln Memorial and legends. Choice surfaces and luster.
