twslisa Pillar of the Community United States 790 Posts	Posted 02/09/2023 10:31 am I love the education I get here!! I'd be very curious how happens as well, but now that I know this is a thing, I googled, and there are lots of threads and videos showing more coins that are heat damaged.

John1 I just watched a video of a quarter being heated and it expanded outwards. Here it is BvjhmblPdec Thanks for your insight! Report this Post to the Staff

Yeah but the diameter of my coin remains the same. Is there something I am missing here? Report this Post to the Staff
lcutler Pillar of the Community United States 1657 Posts	Posted 02/09/2023 4:37 pm The diameter doesn't change, the clad layers just separate and bubble up. I've experimented to get it to happen, and not every coin does it. It may depend on the bond of the cladding or the temperature and duration of the heat applied. Report this Post to the Staff
Dearborn Moderator United States 96214 Posts	Posted 02/09/2023 4:40 pm Quote: the clad layers just separate and bubble up correct, the cladding is expanding more than the copper core, the cladding is on top and bottom not so much on the sides(edges) so it tries to lift up and off of the pure copper core.
