I'd keep it as an excellent example of how bad cladding separation can be.

If you'd like to speed the process up you can try this. I left one in acetone overnight ( when I was using acetone) and the next day all the bubbles had popped.

@kanga I see the term "cladding" and "plating" being used interchangeably for copper-plated zinc cents. I've read the gospel according to Coop: "There is no cladding on a cent. They are plated." — http://goccf.com/t/263243#2222948 . I'm still learning the basics and have been using the term "cladding" myself, but now I'm considering using "electrochemically-deposited copper layer"  |

That one is plagued with gas bubbles, worse I've seen. Reminds of a bad sunburn I had when I was in elementary school, ouch!  |

Isn't the main difference in how the blanks are produced why the terms are not interchangeable? The "Cladding" process applies a layer of CuNi to the stock plate, of which then the "blanks" are cut. The "plating" process adds the copper after the blank is cut from a stock sheet of zinc. Bother then go through an "upsetting" process to make the proto-rims. The difference here is the rim. If cents were"clad" you would see a zinc/copper "sandwich". Accuracy will get ya every time folks!

The "plating" process adds the copper after the blank is cut from a stock sheet of zinc. This is correct. That being said, your basic premise is also correct. Clad coins show their core on the edge because cladding occurs before the punch. Zinc cents show no core because they plating occurs after the punch. For what it is wroth, the 1943 steel cents were plated before they were punch, so you could see exposed steel on the edged. |
