Roasting Coins By An Open Fire

This is what happens to coins placed under the electric element of an oven heated to 450 degrees F.

Upper left is normal.

I wonder what they would look like if so BBQed them. Lol

 

Improperly annealed.

 

So, you're the AT culprit that has all the newbies in an uproar.

 

Hello Esty

 

Any before shots available?

 

They were all normal, that's why I included the "control" cent in the upper left.

 

Yeah, just circulation normal varies. Still a very interesting result.

 

...and, you notice, not always the same. Small variations cause different results.

 

How long did you broil them?

 

If you got them graded, I wonder if you would get the special "genuine broiled" designation?!!?!?

 

I’ll have fries with my broiled coins.

@Kentucky May I ask how long your process took? I'm thinking of trying this on my own as an experiment in my toaster over which goes to 450 degrees. It might turn out differently as it has a much smaller space to work with. Thanks.

 

I've mentioned before that I have a huge Fresnel lens. Under direct summer sun, and at the point of maximum focus, it can boil the zinc out of a Zincoln.

If I were a lesser man, I'd use it to roast coins to a rainbow finish, then list them on eBay as "not AT, just left in the sunshine"...

 

450 degrees and when the thermostat kicked off, I took them out (be careful!).

 

Hmmmmmmmmmmmmmmmm

 

Regular electric oven, put the coins on some Al foil directly under part of the element, set temp to 450 and turn it on. When the thermostat clicks off as it gets to temperature, I slid the Al foil onto a spatula and removed them.
