1964 Lincoln Cent. Struck on a Copper-Nickel Clad Dime Planchet. EF-45 (PCGS). Brilliant and satiny, this attractive silver-gray example retains faint traces of mint luster that are best appreciated when viewed with the aid of direct lighting. The wrong planchet feature has resulted in isolated softness of detail both in the centers and around the peripheries, but most major design elements are sharply defined. This is a scarce Mint error, and also a particularly curious one since copper-nickel planchets were not intended for regular issue production until 1965. In 1964, when this specimen was presumably struck, the Philadelphia Mint would have been using 90% silver planchets for dime coinage. A transitional wrong planchet error, as such, and as noted on the PCGS inset.
