Dug Edward 3rd quarter noble...

DinoUK

....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 ressurected.
It's still not perfect, and probably un-saleable, but heck...it's mine.

Before....



And after....

What on earth?!!? Or rather how on earth did you manage to beat that up straight?!?!?!?!?! Must be the gold property that's mallable

omg that rules.

...actually, after about 600 years in the soil it's surprising how tough that coin was. It was a lot harder to straighten than the silvers I have done. I had to anneal it twice before I dared to hit it. lol.

Oh it's definately saleable! I used to have one a bit like that, but it had a big chip out of the edge and i bought it! AND i managed to sell it too for about £30 less than i paid for it. So yes they are sellable!


I like it.

I'm impressed not only with the coin, but also your successful salvage efforts. Could you please go over in detail the process? Thanks!

The Chip pan method of straightening is:-

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.

I see you're a true conservationist!!! 300 degrees is pretty hot. What's the melting point of gold? And obviously it's not hot enough to mar the features and writing of the coin. Spectacular job with this coin!
