Are you trying to find Proofs in circulation? Do you know the identifiers of proofs ? For instance, a quick search comes up with these descriptions that help you understand the difference. ==> https://www.davescollectiblecoins.com/blog/mint-vs-proof-sets-what-is-the-difference/ ==>https://www.providentmetals.com/knowledge-center/collectible-coins/proof-vs-uncirculated-coins.html ==> http://www.lincolncentresource.com/Proofs.html once your read, and reread the information I recommend that you BUY (yes, you read that correctly "BUY") a few Proof coins in each denomination. Then you can COMPARE them to any change that you may find in a field or parking lot against them. And be very careful on every aspect of the coin itself. Not just that someone polished it and it looks shiny .. there's so much more to it than just it being shiny.
I have a 1976 prof set. I compared my dime to the mint set. They both have thAt gold shiny tint. And i haven't shined it or cleaned it.
Also the image is more detailed and the ridges on the side r perfect. It stood out thats y i asked for. Input
I have proof sets. i know that its unlikely to find one of these dimes in circulation, that is y the condition this coin is in and the similarity to my proof strike has me asking for input
In 1971, a very small number of proof nickels, estimated to be around 1,666, were struck withount the S mintmark in error. Similar errors ocurred with dimes in 1968, 1970, 1975 and 1983 and with cents in 1990. Any of these no S proof errors are quite rare and valuable. So if your coin is a proof, you have something. As for grading, I am 50/50 on this one. If this is a 75 no S and you are selling, a dealer or collector knows what the value is, and you save the grading fees. On the other hand you may want to have the coin authenticated as legitimate.
still looks nicely polished to me especially since the LIBERTY letters and rim are also polished just like the fields ... but hey, send it into PCGS because this would make .. what? number 3 found ? ==> https://www.pcgs.com/top100/coin2.aspx ==> http://munciecoinandstampclub.com/i...o-s-roosevelt-dime-worth-thousands-of-dollars
Initially I thought cleaned/ polished and someone may have switched coins to sell the set. (Or to just keep the proof in place of a business strike 75-P dime). But you never know. Anything is possible.
