75% Copper, 25% Nickel
The 1882 Three-Cent Nickel is a scarce, low-mintage issue that is difficult to locate in any condition, even in grades as low as Good. In fact, it would seem that more Proof examples have survived than Mint State versions, which is the opposite of the vast majority of U.S. coins.
Among the 84 Mint State examples certified by PCGS (as of September 2012), the most "common" grade is MS-64. The finest examples are eight MS-67s (which gives several people an opportunity to own a Top-Pop coin).
