PCGS 1982 Lincoln cent struck on a Philippine 5 sentimos planchet. The coin is struck on the planchet of the 5 sentimos, which is an unusual, scalloped shape. This shape is the curved edge visible on the coin, which is highly unusual as an off-metal planchet type. Very few examples of U.S. coins struck on planchets of this shape are known, and they are extremely tough to find.

Rare, with just 3 or 4 known for cents struck on these 5 sentimos planchets with the scalloped shape still intact (metal flow often obliterates it.) 

PCGS AU details and lightly cleaned. The coin has moderate hairlines.
