Don't think The History Channel is correct on this point. While certain applications requiring a very tight bond still use explosive bonding, cupro-nickel/copper clad is produced by roll-bonding. See www.cladit.com

If I recall correctly, the reason for the clad was to maintain the electromagnetic properties so coins would still work in vending machines.

Dime from Hawaii, dated 1883 and is in what I would call AU condition.

OK, missed it. Value maybe around $75 with the solder spot. Do a search on eBay. Not rare or hi value. I wouldn't bother fixing it, just eBay it.

More great feedback. As I don't want to ruin the coin and It would appear that I most likely don't have the equipment necessary to properly remove the solder perhaps I should just leave it alone. I don't know the value of the coin but I guess that I could most likely just reduce it by playing with the solder.

As a former engineer in the metals industry, I've been following this thread with some interest. FWIW, I would not try any of the methods suggested. I also would suggest you not "play with the solder". If you don't know what you're doing you will ruin the coin. This may not matter since you haven't revealed what the coin is (gold, silver, copper) and the piece may be of low value. If it is and you don't mind the likely outcome, go for it. Otherwise either leave it alone or send it to the pros - Stockton or NCS. They have the techniques to do this properly with the edge going to NCS.
