Greenstang Posted January 22, 2022 Share Posted January 22, 2022 I take it you are referring to picture #3, gets confusing with all the pictures. If that is the case, then it looks to me that the markings are raised which means that it would be glue or some like substance on the coin. Try giving it an Acetone bath for 24 hrs and see if that will remove it . GBrad 1 Link to comment Share on other sites More sharing options...
Clay1492 Posted January 22, 2022 Author Share Posted January 22, 2022 Sorry about that mess with the pics. Still trying to learn how to properly use this. Trying again. thanks. Link to comment Share on other sites More sharing options...
GBrad Posted January 22, 2022 Share Posted January 22, 2022 (edited) Go back and look at what Greenstang recommended. If the areas are raised then it is probably an adhesive that should come off if you soak it in Acetone. If the areas are incuse then it is most likely PMD. It's hard to tell in pictures what is raised and what is incuse. Edited January 22, 2022 by GBrad Link to comment Share on other sites More sharing options...
tj96 Posted January 22, 2022 Share Posted January 22, 2022 I'm with @Greenstang & @GBrad glue, some type of adhesive or maybe epoxy. GBrad 1 Link to comment Share on other sites More sharing options...
Mohawk Posted January 22, 2022 Share Posted January 22, 2022 I'm with the others.....I'd try an acetone bath, see what kind of results you get, and go from there. GBrad and tj96 2 Link to comment Share on other sites More sharing options...
Chris Mikesh Posted January 22, 2022 Share Posted January 22, 2022 Interesting... Acetone may release it if indeed it is an adhesive of sorts. But (me personally) I'd leave it alone. It's a good curiosity. However, I can't help but notice that the stars, arrows, and other features are still there. Consider this: if it is incused (damaged) with something external in the circulation life of the coin, I think it would have more damage to the detail. Also, the copper could have been exposed if it was exterior damage. MAYBE (we'll never know for sure) the blank had a problem before striking. Curious that there are spot on the obverse, and so much damage on the reverse. Too bad we don't have 3d pictures. I also have a Kenedy (1969 S proof) that is rusting! No, it's not magnetic, but it looks (through 10X magnification) like something was in the silver causing the corrosion. All I'm saying is, I have a curious Kennedy too. Maybe it was the same guy striking the coins eating his lunch and was transferred from San Francisco to Phili. Naaah! God Bless, Chris Link to comment Share on other sites More sharing options...

Your 1969-S Proof I don't believe could possibly rust granted it was struck on its intended planchet. Being comprised of 40% silver and 60% copper, neither one of these elements are predisposed to, or are able to, rust. I'm not a professional metallurgist but unless your half somehow contains iron, which it shouldn't..... I don't see how it could actually rust.

Mohawk Posted January 22, 2022 Share Posted January 22, 2022 Greg's absolutely correct.....silver and copper cannot rust. It's metallurgically impossible. They can develop corrosion of other kinds, especially copper, but they can't rust. My guess is that your coin has some kind of corrosion related to the copper content. I've seen that on 40% Kennedys before, typically along the edge of the coin. If you post photos, we could likely tell you more about what's going on.

Yes Chris, I think @Mohawk has a great suggestion here. I would personally love to see your Kennedy and what it looks like. As opposed to posting it here on this member's thread, simply out of respect for the original poster, why not make a new thread for your coin. I'm sure Mohawk and others would like to see it as well. I'm sure there are other members who have not read down this far on this particular thread to see what we are talking about now. It sounds pretty interesting and who knows, if you have a 40/60% Kennedy half, and it does in fact have rust, you may have something of value. I have never heard of a silver proof rusting. I could only assume from what you described that you may have an off metal planchet error of sorts. If you do decide to make a thread for it, make sure you add the weight of it in 100th's of grams if you are able. Just MHO here and ya never know......

FYI Just to clarify. 40% silver coins have a 3 layer clad composition. The outter layers are 80% Silver and 20% copper while the inner core is 21% silver 79% copper.

Just to set my thought processes straight here, if these proof coins do not contain any iron, and they only pure silver and copper even in the layer forms as you described, how could rust could happen if there's not any iron in the mix? Especially if an entire coin has rusted. To me that means it would have to contain a considerable amount of iron??? Thanks. Link to comment Share on other sites More sharing options...

I've never really seen an entire coin rusted. We've seen a lot of coins here entirely corroded, which "I think" is different from rush. I could be wrong though. The only coin I've seen with real rust on it has been a 43 steel cent. Link to comment Share on other sites More sharing options...
Hoghead515 Posted January 23, 2022 Share Posted January 23, 2022 Ive got a counterfeit draped bust dollar that is rusting. Sounds like if his half is rusting its a counterfeit. But why would someone want to go through the trouble of counterfeiting a kennedy half dollar? tj96 1 Link to comment Share on other sites More sharing options...

Could be toning that's mistaken for rust, or the coin could have been in contact with iron and the rust stained the surface. Until we can see the coin, everything is just speculation.
