Spence Moderator United States 34397 Posts	Posted 07/11/2019 10:52 pm @SF, for sure not a Cud for the reason explained by @fuzzy. Could you please post a close-up pic of this region of the coin? When I enlarge and enhance it from the pic you already posted, it gets too pixelated to see what you have. Thx.

sel_69l Bedrock of the Community Australia 21786 Posts	Posted 07/12/2019 04:18 am If it is hard silver solder, there should be some evidence of heat stress at the site of the blob. I don't see that in the pictures, and therefore to my eye, I would assume :- die chip. A close examination with a high powered loupe may reveal different to what I see. Report this Post to the Staff

Sap Moderator Australia 16816 Posts	Posted 07/12/2019 9:21 pm These coins are made of nickel-plated steel; a tiny pinhole in the plating caused by a deep scratch or other damaage can cause the underlying steel to form a "rust bubble" beneath the surface. This would always be my assumption whenever I saw a mysterious "bubble" on a plated-steel coin. In this case, you can tell it's a rust bubble because it is apparently "beneath" and "lifting up" the ring of denticles. A die chip would obliterate them. Rust bubbles are, of course, post-mint damage, not a mint error or variety. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff

Errers and Varietys Bedrock of the Community United States 73937 Posts	Posted 07/12/2019 11:40 pm Hey, Sap, can that also be called a plating bubble as well, or is that completely different from this? Just wondering out of curiosity. Errers and Varietys. Report this Post to the Staff
