The 1954- D Lincoln Cent is very common in circulated grades. There are still some original rolls left but getting harder to find. Coins in MS64 quality seem to be abundant in open rolls or in bags. In MS65 it becomes a little harder to find and these are usually cherry picked from rolls and set aside and many times sold individually by dealers. In MS66 they are scarce but yet, still thousands of them are available. Examples in MS66+ are very difficult to find probably less than a few hundred exist. In MS67 condition they are very scarce with possibly under 100 examples known and none being graded higher.
