Looks like the beginnings of zinc rot to me. Air is getting between the copper and zinc layers and starting to oxidize.

Whatever that is on the obv would be a Cud since it involves the rim, but I agree that it is more likely a gimungous plating blister. "If you climb a good tree, you get a push."

Thank you josephm99 and Spence for your explanations. How does one differentiate between a die chip and zinc rot?
Spence, is plating blister another term for zinc rot?
Thanks,
Co1ns

Press on the raised areas with a toothpick or, since these are so large, your finger. If the bubbles collapse or can be depressed they are just plating blisters or rot that is causing the copper to rise.
My first thought was blisters as well but they have well defined straight edges to them which is similar to large die chips.
Good luck and let us know.

Looks like something is glued onto the coin? And then hit with a hammer, making the reverse bulge out.
Zinc rot/split plating often shows a gray color where the air gets into to affect the zinc.

Hey everyone, So I tried depressing the raised area and nothing happened, it's rock solid. Also what do you think about the other raised area at the bottom of the memorial, see pic. If you don't mind my asking, why would these not be considered die chips? Is it because of their size? Once again thank you all for helping clarify.  |

The discoloration and circualtion damage makes the two larger areas suspect.
But the fact that they didn't "deflate" when compressed makes me wonder if it could be die damage of some kind. The two larger ones line up with each other and the one on the steps does look like a chip.
You could submit it to cudoncoins and see what they say (to find out if it might be an interior die break).

Looks like incuse damage on the reverse. Maybe ab opposite side raised area to the right of the ear area on the face? Push though to the opposite side?
