A fully lustrous 1919-S Lincoln cent graded Mint State-66 Red by the Professional Coin Grading Service (PCGS) sold for an astounding $19,550 (a hammer price of $17,000 plus a 15-percent buyer’s fee).
Heritage described this coin as “the single finest representative of this issue known to both NGC (the Numismatic Guaranty Corporation of America) and PCGS.” Still, it is a 1919-S, not a 1909-S. And, with a mintage of nearly 140 million, it has never been mistaken for a rarity. In fact, it has one of the highest mintages of any Lincoln cent produced before 1920.
With this and other so-called “common-date” cents in the Heritage auction, however, the crucial figure wasn’t the number produced by the Mint, but rather the number certified in very high mint condition since the start of the “grading revolution” in 1986.
In the case of the 1919-S, this is the only specimen ever graded MS-66 Red by PCGS or NGC, with none graded higher. Thus, this has a legitimate claim to being the finest-known 1919-S Lincoln cent – a true condition rarity if ever there was one.
Obviously, ‘19-S cents weren’t well struck and fully lustrous even on the day they left the Mint, so not many examples existed to begin with – and over the years, the number has been winnowed to just a precious few by the ravages of time and attrition.
