I’ve come across a dime that is damaged somehow. I’m wondering if there is a possibility it is was caused at the mint and if so, how, or if it was damaged in circulation. I don’t know of anything that could do this kind of damage short of maybe a chemical reaction of some kind. I would’ve leaned more towards after mint damage but the side profile is as straight as any other dime, not warped from a side profile view at all. It seems to be “bubbled” in areas all over. Any ideas?
Heat damage. Not a mint error of any kind. Don't over think it. There is a simple short answer for most damaged coins.
@AikoNavs I see you live in Texas. That's cool. So do I. What city do you live in? I'm in Katy, just on the West side of Houston. Don't hesitate to call on any of us for help with any coin questions. You can "call" someone by tagging them like this : @Hookman
agree with Paddy - heat damage of some kind - regular coins that get hot tend to bubble at times because they are clad. Looks like the bubble was pushed down and put on buffing wheel to get that dime appearance
PMD, post mint damage, meaning it happened after it left the mint. The dime was subjected to high heat to cause that damage. BTW welcome to CT.
Campfire experiment or perhaps a drop or two of acid placed on the obverse and wicking to the reverse (kind of looks like evidence of a meniscus on the obverse, but could be a witness mark of a bubble pushed back as noted above). If it's acid damage, your dime would be a little thinner, lighter. Weighing your specimen and comparing it to mint specifications would help you vet that possibility.
I live in San Antonio..not too far from you. I travel to Houston often because my husband is safety for some rigs out that way in Mount bellview. I’ll give you guys a shout when I’m in the area. Thanks!
