Mystic Wolf New Member United States 30 Posts	Posted 05/13/2025 7:28 pm Does anyone happen to know what causes this type of toning (as opposed to the more common circumferential toning)? This isn't the best photo, but it was the closest I could get to showing the fascinating way it hovers around a specific design element, almost as if it's caused by a giant liquid bubble underneath the surface. I have a quarter that's similar, and am trying to figure out why I find them so intriguing. *Toneless(?) reverse image included solely for contrast Report this Post to the Staff

I swing a metal detector and have a knack for finding dirty old coins.

Quote: More of a stain - not toning. Well, that's certainly unanimous, and fits my initial thought! What threw me is my inability to scrape (via fingernail or toothpick) or rub it off even the tiniest bit. So I guess probably some form of staining...good thing I like it, lol Report this Post to the Staff
Mystic Wolf New Member United States 30 Posts	Posted 05/13/2025 11:18 pm Follow-up question: If you lightly run your finger (or the back of your fingernail) across the coin, you can feel there's no break in the smooth surface of the lamination when crossing into/out of the stained area. There is, however, a DEFINITE change in the surface texture immediately outside the confines of the stain, where you can feel the lamination has lifted off/separated from the coin, creating a very slight bubble just past the stain that ends at a faintly visible outline (it's the reason I started associating the stain itself with a "liquid bubble"). It's not the clearest pic, but the arrows are pointing to the outline where the "bubbled" lamination ends. Out of curiosity, what type of stain causes lamination to actually separate from a coin? And are there multiple stains that achieve this same effect? Report this Post to the Staff
