Double-denomination 1988 Lincoln cent struck on a 1988-P Roosevelt dime. The coin shows the designs of both coins, but is the metal of a dime. A double denomination occurs when a struck dime is fed into a press and struck with cent dies. Somewhat scarcer date for double denomination 11c coins, and this example shows strong design detail from both the cent and dime, which adds to the coin's overall appeal.
ANACS MS-64 with some light toning.
