This ones for the Veterans all input is very much appreciated Well this one has me stumped thinking what could cause this effect. There are wavy indentures on the coin when looking at it straight on. When you flip it 180 degrees it is going inward towards the other side that looks like plating issue this coin is in and out all over the coin and matching up obverse and reverse so zinc rot is not an option and there is no planchet abrasion just curious if this is a common error or damage caused by ? I cannot find this type of coin anywhere. I have looked high and low any input would be greatly appreciated thank you very much this site hands down is t
he best I feel confident the correct answer will be found thank you again for all you do. My thought on this one was the inner zinc filling wasn't solid enough for the plating causing it to lift inward and outward leaving this effect

Caused by heat
Like a blow torch or oven wouldn't that leave a different coloration of the planchet plating everything I have ever seen heated shows colors different from what we are seeing here
If not zinc rot blisters then possibly exposed to heat and the copper plating has “bubbled” away from zinc core.
Where ever the bubble is it is pushing from the other side of the coin perfect match all over the place look at the reverse and obverse one sides out same place on the other is in so lift is possible but the zinc follows the form of the coin I tried pushing on the plating and no dents occurred thanks for your input greatly appreciated.
Stop hiding behind the flag!!! How very very very disgustingly sad. This is just a damaged coin, damaged after leaving the Mint. If somebody would take it in change as one cent, you would be lucky.
You my friend are having a bad day Hey these colors don't run dust your cowboy hat off. Take up a sit down in your easy chair and grab a book and read the meaning of Veteran. I stand with the flag not behind it you best stay off that horse your riding and take up another hobby like coin collecting you might be good at it. You also need a lesson in respect which you completely lack and other things I will not mention.Veterans are the one's who fight for this country and have fought for this country to keep you and I free I love my flag and stand beside it not behind it. . God bless every Veteran it's people like them that make this country great
You are a shill for money and mentioned the veterans to hide your ill intent. Shameless.

I don't think that's what he meant.
Post Mint Damage. I'm not sure we care how it was done.
Zinc melts at 787F/420C. That's only a little hotter than the broiler in your oven.
I know from experience (when I was young and stupid, now I'm not young anymore
), that a torch or even the flame on a gas stovetop, will quickly cause the zinc to liquify and break through the copper coating. The trick was to hold it far enough away from the flame source until the plating just started to ripple. Nitric acid does really cool things to clad coins, but that's a different discussion 
Post mint damage....As to the cause, it will be speculation....heat and pressure combination likely...Cheers, RickO
Post mint damage ... nothing more.
PMD - it didn't leave the U.S. Mint looking like that.
