Brandmeister Pillar of the Community United States 6454 Posts	Posted 06/21/2024 4:35 pm Having just settled the 1981-S pair of mint marks for my proof nickel folder, I moved on to the 1979-S nickels. I thought that I had settled these two coins, but when I checked them again, now I am not so sure. One is clearly a Type 2 mint mark. Not sure about the other nickel. It was sold as Type 1 on ebay, but I don't think it looks like MMS-009/004? The mint mark seems to have two ridges and a really groovy shape. Definitely 1979-S Type 2: Not really sure: http://www.varietyvista.com/04b%20J...20Styles.htm Report this Post to the Staff

jbuck Moderator United States 187637 Posts	Posted 06/21/2024 4:37 pm I am going to say they are both Type 2. The Type 1 is more blob than S, with serifs that melt into the body of the S.

-makecents- Pillar of the Community United States 8726 Posts	Posted 06/21/2024 5:26 pm Definitely a type 2 but looks like the punch is messed up already or isolated MD. Maybe it wore out quickly and that's why there were two types in 81? -makecents- Report this Post to the Staff
Brandmeister Pillar of the Community United States 6454 Posts	Posted 06/21/2024 5:27 pm To me, the second one almost looks machine doubled. But the 79 looks untouched, so maybe that's unlikely. Does Machine Doubling even happen on proof coins? Edit: -makecents- beat me to the punch. Har, har. Edited by Brandmeister 06/21/2024 5:28 pm Report this Post to the Staff
-makecents- Pillar of the Community United States 8726 Posts	Posted 06/21/2024 5:30 pm Here is a link to isolated MD, but I don't know enough about proofs to answer your other question. I don't see why it could not also happen with proofs though. LINK https://www.error-ref.com/isolated-...ne-doubling/ -makecents- Report this Post to the Staff
Brandmeister Pillar of the Community United States 6454 Posts	Posted 06/21/2024 5:41 pm That's an interesting ErrorRef.com article. So basically if the mint mark has been punched deeply into the die, when the coin is struck, the mint mark will protrude a little higher than other devices. That can allow MD and chattering die to affect only the mint mark without disturbing anything around it. Visually, those article images seem similar to what we are seeing here.

-makecents- Pillar of the Community United States 8726 Posts	Posted 06/21/2024 5:48 pm I can't tell from the angle of you pic. Is it all around the mm or just the right side? If it's on both sides, it might be as I said, possibly a worn punch already. -makecents- Report this Post to the Staff
-makecents- Pillar of the Community United States 8726 Posts	Posted 06/21/2024 6:03 pm Here is a good read and the type 1 looks like yours. LINK https://www.pcgs.com/news/differenc...incoln-cents -makecents- Report this Post to the Staff
Dearborn Moderator United States 94728 Posts	Posted 06/21/2024 7:24 pm I'm mixed on this MM. The top of the mm spine is flattened out, but the bottom half of the spine appears to be a narrow pointy spine A better in focus image may help Collecting since 1972.
