1999 Lincoln Cent--Bonded Die Cap--Mint State (Uncertified).At least four coins are involved in this bonded die cap error, the planchets distending and splitting as they curled up around the obverse die. The most complete impression is seen at the base of the cap, where a nearly full obverse is evident on the exposed zinc core of one of the planchets. Approximately 15 mm tall at its greatest height.From the John Whitney Walter Collection. Acquired from Anthony Terranova, June 1999.
