....here are the before and after pictures of an Edward quarter noble I dug.
It was pretty bent up, but using the tried and rested chip pan method it was resurrected.

That is one sweet coin you have there. Glad to see that it straightened out okay!!!
I dug a US half dime once that was bent almost double, and was able to straighten it out (mostly) by putting it between a couple of wood blocks and tapping it with a hammer. I was worried I'd break it in half but it did OK.
and by the way, Dino?
I hate you.
What is the chip pan method?

To straighten a coin, first you have to re-anneal the metal. What happens when a coin is bent, is that the molocules of the metal on the inside of the crease have been compressed, and the ones on the utside have been stretched.
Before you attempt to open the coin, these have to be re-alligned by heat, and a heat as near to 300 degrees.
Obviously water will only go to 100 degrees, so I use the chip fryer.
I get it as hot as I can before flames...really smoking.
I then toss the coin in and get it up to temperature, then take it out with forceps and toss into cold water.
Then back into the oil and when hot, straighten a little with a small wooden pastry roller. Repeat until flat.
If you don't re-anneal first, you take the risk of snapping the coin.
Another way with silver, is to use a gas flame until cherry red, then cool...this is a bit extreme, and you really have to watch the temperature to avoid melting the coin.
Thanks!.Im extremely impressed.

It's a good thing I was lucky when I straightened my bent half dime. I was worried about snapping it. It never ocurred to me to anneal the metal.
