How to separate with minimal damage

[Donna(NJ]

Doing some clean up and found these two silver coins fuzed together. They are not dimes as they are smaller and thicker. Can't remember where I found them. Very pitted like they came out of the ocean. I beach hunt 90%of the time. I also hunt in England. I know I could smack it with a hammer but don't want to destroy if there is detail inside. It's been in a tumbler twice but still stuck. Any ideas??

TIA

Donna, I’d like to help but I’m like the owl in the lollipop commercial trying to figure out how many licks…

That sound great !!! Very doable. I should have Googled it, like my sister-in-law always said. Propane and ice water. Hopefully !!!

Thx much,
