Another newbie post here but I need input again. I found these 2 coin roll hunting. The first is a 1998 that has a frosty white look to it. Is this possibly a proof or something?? Second one has a very thick rim that touches the letters. Not sure if that is common or not? What do you guys think? Thanks in advance!

There are no 1998-D proof Kennedys. Yours has something on it. I've seen various rim widths on 1971 halves (there are a LOT of 1971 halves). I'm not sure what causes the variation, but I don't think it's significant.

1998 proof Kennedy halves were only made in San Francisco. Your coin was minted in Denver so it’s not a proof. It has some kind of damage to give it that look. It seems a lot of 1971 halves have wide rims like that. I don’t know why but it’s common for that date.

Not a proof. Proofs were minted in San Francisco while uses is a Denver. Something has been applied to the surface after it left the mint. Not an error. The 1971 looks normal to me, except for the wear.

Thank you for the info. Back into the coin rolls they go then! Back to the bank. Thank you for this very helpful post. Very welcoming to a new guy. Thank you for the info now I know proofs only come from San fran mint I was not aware of that. Thanks.

[QUOTE="detectorben, post: 4525576, member: 89073”]Thank you for the info now I know proofs only come from San fran mint I was not aware of that.[/QUOTE] There are some non SF proofs. Any proofs 1964 and older are Philadelphia minted. Also, there have been some other mint proofs as special releases. But for the most part, S mint has been the only modern circulation coin proofs.

I think you should invest in a Red Book. That will tell you the information you need to know about where Proof coins were minted. You could buy an old one (but not too old) for less than the current cover price which is something like $16.
