1975 No S Proof? Looks Cameo To Me

That is a business strike minted at the Philly mint not a proof.

That is a business strike cent, not a proof.

If it were a rare and valuable no-S proof strike then you just did serious fingerprint damage to it by holding it in your hands.

yeah, sorry not a proof, so no Cameo.

The 1990 "No S" proof Lincoln cent is among several other proof "No S" mintmark coins. These include the 1971 "No S" Jefferson nickel, the 1968, 1970, 1975 and 1983 "No S" Roosevelt dimes, and the 1976 "No S" Type 2 Eisenhower dollar. There is no 1975 no s proof cent worth extra money. https://www.numismaticnews.net/arch...es-rich-no-s It's estimated that fewer than 200 proof 1990 "No S" cents are known so thats unlikely to show up as well in sets.

There is a 1975 no s dime, maybe thats what you thought? Although Proof coins were being struck at the San Francisco Mint at the time - the 's' mint mark, the Philadelphia Mint was responsible for making the Proof dies (and adding the mintmark). Apparently, at least one die was sent from Philadelphia without the mintmark, and a small number of PROOF "S"-less Dimes were struck and released before the error was discovered. The 1975 "S"-less Dimes are so rare that they were not even discovered until 1978, when two examples surfaced. I'm not aware of any others since yet. The mint mark letter P does show up on Business Strike Philadelphia coins after 1980. From 1946-1979 no P was used however so there is alot of confusion because you will certainly find lots of these no P dimes for 1975 produced for circulation which are not the same as the proof missing the mint mark. Proof coins are coins produced by the United States Mint using a special process to impart maximum detail onto the struck coin, to present the designer's art in its full glory for collectors.

to the CCF and Search the difference between proof and business strike. Once you compare the two, you will know the difference.
