What in the world???

What do y'all think caused this? The bubble on the front is not centered over either bubble on the back.

Judging from the black on both sides, I'd say it was heated with a torch.

 

Ditto. Heat damage.

 

Acetylene torches - somebody just screwing around!

 

And the horrible whizzing on the Obverse took away the blackening from the heat

 

In other words.. Post Mint Damage.. occured after it left the mint. No Value except .50 cents

 

Ya I knew it was pmd. I didn't think about heat. Makes sense.

 

I've tried this, never got my coin to bubble. I was tring wit a 1965 Washington quarter. Anyone know what it takes to get it done...i.e. time, temp...etc?

 

Ah HA - so you are the one!!!

 

nah man, like I said, I've tried. I was using a propane torch tho, I'm wondering if it requires something hotter, like you said..Acetylene. it's a bit of a side hobby...when someone posts a PMD coin and refuses to take the word of experience that its PMD rather than a million dollar error, I like to pull my example out and explain how I did it. This particular one I've not been successful with.

 

LOL I love this. That's my kind of humor right there.

 

*sigh* blowtorch damage. And then a very heavy scrubbing using steel wool.

 

Try it on a Zincoln and tell me if it melts. Or send me a pic.

 

High tempature, and there has to be a gas bubble trapped between the clad layers. No trapped gas, no bubble. This means that not every heated coin will form a bubble.

 

You can melt zinc cents on a gas stove flame....

 

Cool!
