from Bern Sherman
Jaime Hernandez: The 2012 Lincoln cents have a Union Shield design just as they did in the two previous years from 2010 and 2011. Coins are very common up to grades of MS65. In MS66 they become a bit scarce with some searching required. In MS67, they are very difficult to find with few examples available. In MS68, it is the ultimate grade with very few examples known in this condition with none being finer.
