Jefferson on the Wrong Planchet?

Just wondering if any of you had any insight on this nickel. It weighed 3.0 grams. Hopefully the photos are attached.

This nickel was dissolved in a corrosive substance. These altered coins are called "acid jobs" although it's not clear whether the fluid is an acid, a strong alkali, or some other corrosive liquid. I've heard that concentrated phosphoric acid does a number on copper-nickel and copper-alloy coins.

 

I would agree, acid job. A dime planchet is only 2.27 grams si it would have had to have been a foreign planchet plus the image looks more eaten away than weak struck.

 

Thanks Guys, I had a feeling it would be one or the other.

 

Looks like the type someone (me) and many others produced in Chem Lab. No, the Phosphoric acids didn't react suffieciently enough and if not wanting to get caught by a professor, it had to be stronger. The Concentrated Nitric did just find. Naturally, the 3 to 1 ratio of HCl and HNO3, Nitrosyl Chloride could do that in seconds. The tuffy was getting the coin out.
