Error -1980 Quarter with Huge Gas Lamination Bubble

About 20 years ago I pulled this 1980 quarter out of circulation. It has what appears as a very large gas lamination bubble.

Anyone familiar with something like this?

I am going to post it on Ebay but wanted to know a little more about it first.

Sorry about the small photo but I am not sure how to load photos up.

Many thanks - AC

Usually caused by heat being applied--like a torch.

Here is the obverse. I will look for evidence of heat.

If someone can tell me how to post large photos on this forum I will.

However the coin looks perfectly normal and no indication of heat. There is actually some wear on the bubble so I guess it circulated for a while while the bubble was there.

So are you saying that if you heat a coin up it will bubble?

Yes. A torch can make a clad coin bubble like the one in your pic. This is considered post mint damage.

That quarter is not an error;

there may have been a gas
bubble between the outer
clad layer and the copper core;
upon direct heat, it will "bubble"....

A very common occurance to clad
coinage, done by someone with
more time on their hands than
they should have; when spent,
it causes confusion by the finder.

Sorry.......

I am convinced. But it is the first one I have ever seen and I am 62.

Now I will have to see how many quarters I have to heat up with a torch to get one to bubble without turning the metal blue.

BiddlesBank you should set up an account at photobucket.com, its free and will automagically give you a link to the pic so you can post it on boards like this one

Obvious heat error, after the coin was struck. The blue area around the bubble is evidence, as the design was struck onto the coin first, then raised by the heat.
