2005-S 1C, DCAM PR70DCAM 认证号16150624, PCGS号93554

Top coin is 1961 PR66BN, PCGS Memorial Cent Coinfacts Plate Coin. Bottom is 2005 PR70 DCAM. There are two main differences between these coins. First, the composition of the cent was changed to copper plated zinc in 1982. Second, there were several successive design changes to the obverse portrait that took place during the early 1990s, changes in the hair detail, the nose, the eyes, that culminated in an almost completely different looking Lincoln around 1995. The more modern design was eventually done away with in favor of the original in 2010 with the introduction of the Shield Cent.
