I know theres differnt types of proof coins tgough so its worth advice the penny is well struck the fields are clean and the strik(e is strong worth a shot
As @cpm9ball mentioned, the only 1990 Lincoln with no "S" that's worth anything is a proof. They only struck proofs at San Francisco that year, and all proofs should have gotten the "S" mintmark, but a few which were released in proof sets did not. Those are the rare ones. A regular business strike coin from Philadelphia, on the other hand, would not have a mintmark. That is perfectly normal for those. Your coin is a regular business strike Lincoln, not a proof. It was struck at Philadelphia, so it did not get an "S" mintmark (and wasn't supposed to). It is worth one cent. A proof coin would be struck on a polished blank with extra pressure, and have deeply mirrored fields, a frosty portrait, and a very squared-off edge. Once you learn the difference, it's pretty obvious. See the difference here? The coin on the left is a business strike. The one on the right is a proof strike.

You're absolutely right! There are pennies, nickels, dimes, quarters, half dollars and even dollars coins that are proofs. Chris
Yes, like matte, satin and mirrored. But since 1936 they have only made mirrored. The cameo mirrored proofs started consistently in 1971 or so.
I see I'm a little late to the thread but here goes anyway. No. It's not even worth a shot because "Proof" is a manufacturing process and not simply a "well struck coin". The value in the 1990 No S Lincoln is the fact that the proof coins are supposed to go thru an extensive QA Process to insure that no mistakes are made. The slipped thru. In 1990, Philadelphia did not put a "P" mintmark on the Lincolns they produced. For that matter, a P mintmark has NEVER been put on a Lincoln Cent until this specific year which marks the 225 Anniversary of the US Mint. What you have is a Lincoln Cent manufactured at the Philadelphia Mint and you can buy rolls and rolls of them in BU condition for about 7-10 bucks.
I fail to see what the PCGS webinar about grading proof coins has to do with anything in this thread, since your coin is NOT a proof.
