Thanks guys. Exactly my thoughts. Already in a 2x2.

Now that's a stellar example of plating issues. Very cool!

I think it looks cool as well. Will it continue to rot even in 2x2?

Wowser, that's a severe case! I have some '83's with blisters but dayum that's wicked nasty. "Hey I have a great idea, let's make a new one cent US coin. We'll make the core from zinc, and plate it with a very thin layer of copper. Yeah, Yeah that's it. What a great idea!! We're gonna be famous."  |

Here's a little game for everyone. How much will the US Treasury be ahead once all the zinc cents turn to dust.
42.5 years of zinc cent production sure adds up.

wow, that zinc is just aching to burst out. I could be wrong, but I think this isn't your usual "zinc deterioration" blisters. All indications are that the OBW roll this came out of was stored properly and wasn't subjected to humidity or moisture. There are no perforations or weakness in the copper plating that I can see. Most of the other coins in the roll had very few, if any, blisters on them. IMHO, I think these blisters are caused by the copper plating not bonding properly to the zinc substrate because of some type of contamination on the surface of the zinc. Temperature differences may have affected some trapped gasses or caused the two different metals to expand at different rates Words of encouragement are one of the major food groups.

However it may have been caused, it does include the copper not bonding to the zinc.
Just to add another theory to the cause of the blisters...Someone could have cooked this
Zincoln, at a "certain temperature", and caused the plating to begin to separate from the zinc in this manner,
perhaps without causing any additional, visual heat damage. Just the right amount of heat, for just the right amount of time.

Tacc, I was actually wondering if this would result from putting a zinc cent in the microwave.
Note: DO NOT PUT A CENT IN YOUR MICROWAVE.
I know most of you folks are responsible adults, but it's the Internet, and I don't want someone ruining their microwave or burning their hand on screamingly hot metal.
I think what Pete said is more likely to be correct. The copper foil isn't actually bonded to the zinc core. Maybe it was dirty or splattered with something. Alternately, maybe the zinc was rusted or impure, and this is a slow gas reaction bubbling up the plating.

Yeah it could be anything. We are dealing with an imperfect mint product here, and
it would be difficult if not impossible to conclude what exactly caused such extreme blistering.
As mentioned, I have many "blistered" Zincolns and most are from '83 & '84, nowhere near as
afflicted as Pete's coin here.
The microwave approach sounds fun. Not suggesting trying this at home, but from previous experience
with aluminum foil and steel forks accidentally placed in the microwave, it usually causes severe Arcing form
the metal to the interior walls and the resulting burn marks.

They will grade it if you send it in. No idea how they would come to a conclusion. Lol. Cool coin

Nice! I have found some really bad ones, (or good ones, depending on how you look at it), but nothing this severe or still this intact.
