Incredible Altered Zinc Cent. No idea how they did this.

This is a genuine 2006 cent....



...and below is the other side.



There is virtually no zinc at all on this side. I mean, it is on the atomic level pretty much.

How someone removed just the obverse layer and did very little damage, combined with not affecting the coin's designs and details, is truly amazing.

As a major error collector as well as other neat numismatic items, I have to say having just a complete side of copper plating from a zinc cent is super cool.

There is a way to dissolve the inner zinc just leaving the copper shell. Then you split the shell and what is left is what you have shown us.

 

Here is one video -

 

Yep, strong alkali (lye in water) will gnaw right through that zinc, without touching the copper. I'd grind off the reverse first to remove any chance of pressure buildup. (You're seriously tempting me here -- a chance to do some chemistry AND speed some Zincolns to their inevitable fate?)

 

Why, what's stopping you! And while you're at it, can you make me a reverse?

 

Is the other side incuse? Like its the copper but literally backwards? That's crazy.

 

Yeah! Crazy, ain't it! And how are you?

 

Man, I'm good. Working on a new/old project. Will reveal soon

 

Whatever floats your boat, man...
