This is the second year that the Mint produced Brilliant Proof Lincoln Cents. It also has the second lowest mintage in the non-error Brilliant Proof Lincoln Cent series. The 1990 No S Proof Lincoln cent might have a lower survival rate but that coin was struck as an error and not as a regular Proof coin. Most examples probably still survive since they are proof coins and weren't intended to go into circulation. Out of the survival rate, most examples appear to be in PR64 to PR65 condition. Examples in PR66 are considered scarce with about 300 examples known more or less. In PR67 they are really scarce with about 2 to 3 dozen known.
