Frff Posted Saturday at 09:51 PM Author Share Posted Saturday at 09:51 PM Never mind I just realized it's a 1990 with no s mint mark but is this still a proof Link to comment Share on other sites More sharing options...
Greenstang Posted Saturday at 10:03 PM Share Posted Saturday at 10:03 PM Not a proof, just a Philadelphia mint business strike. Link to comment Share on other sites More sharing options...

Sandon Posted Saturday at 10:07 PM Share Posted Saturday at 10:07 PM (edited) I'm glad that you realized that it was a few thousand proof 1990, not 1991, cents that were erroneously struck from dies that lacked the "S" mintmark. To my knowledge, all of the 1990 "no S" proof cents have been found in mint sealed proof sets, not among circulating coins. No 1991 proof coins are known to exist without the "S" mintmark. No, your 1991 cent is not a proof. It has normal, bright "cartwheel" luster for an uncirculated cent struck for circulation. A proof would have a mirrorlike surface in the fields that would contrast with heavily frosted devices and lettering, as on this 2000-S proof: You might want to go to the U.S. Mint's website (usmint.gov) and buy yourself a current year proof set to familiarize yourself with what modern proof coins look like. You could also buy one or more of the quite inexpensive 1970s to early 2000s sets from a coin dealer. Although every once in a while, proofs that were mistakenly spent turn up in change, such pieces would usually be impaired and of little value.
