This is a first for me seeing anything like this. It's a 1999 quarter with a hump on each side, not in the same location. It's clearly an error but I've looked online and still couldn't find anything. Anyone seen something like this and/or know what the value of this would be?
First, welcome to the neighborhood @Josherho ! There is no question that this coin was subjected to considerable environmental damage. Perhaps @paddyman98 could answer the question about the "bumps" since he is an avid metal detectorist. Chriss
Thank you! I've got quite a few coins, but none as old as I've seen on here. Oldest I've got is a 1900 Indian Head penny. Pretty jealous of what I've seen on here. My thing with coins is errors. I found a 1955 penny the other day and it "almost" looks like it was double stamped but can't find my magnifying glass to confirm. In all honesty it doesn't look like a post error since the limbs on the tree is still the same size as it would be normally stamped. If it were heated they would be considerably wider, thats what i was thinking but i could be wrong (im a metal fabricator). Sadly it is damaged quite a bit but the error is what I love about it.
No question, it was subject to high heat and a bubble formed between the clad layers. There is also a heavy build up of heat scale on the surfaces The metal was stretched when the bubble formed, which could cause the devices to expand or narrow (depending on the location), but any difference in the dimension would be very miniscule and it would be very difficult to measure yet alone see it. It is not a mint error. Get a blow torch and you can make as many of these as you want.
Now that I found my magnifying glass I can see the difference. Looks like this one will have to go in the piggy bank lol
Just because it looks different does not mean it's a Mint Error I want to share this website with you - http://www.error-ref.com Read it all and understand what Mint Errors truly are.
