The Lincoln nickel design probably the most popular of these issues. This is the only Lincoln head pattern produced by the U.S. Mint.
Examples were struck as follows:
Nickel J486/P575 with over a half dozen known including 3 in museum collections and at least 5 in collector's hands.
Copper and/or Bronze J487-J488/P576. These are known on both thin 58 grain and thick 72 grain planchets with about a dozen or so combined known.
