First I thought clad layer issue... Then I turned the coin over and was momentarily "gobsmacked"

I would love some help in confirming my assumptions on this one.

I find the darndest things in coin rolls. This Kennedy looked like a clad error from the front, but after seeing the reverse I began to wonder.

The pictures don't show it well, but the abraded area at the back of Kennedy's head is showing the copper beneath. But if you look at the zoom of that area, there is a suspicious bubbling look. Is that indicative of acid damage?

The reverse is a piece of work. The copper imprint on the top of Independence Hall looks like it was impressed with the back of a penny. It is definitely copper colored, and it is slightly rough as if some of a penny's copper was left behind. You can even read "States" and part of "E Pluribus Unum" backwards.

There is also an odd "river" mark through the middle of the Hall with some of the copper beneath showing through.

Am I right in thinking this was someone's shop experiment?

I'm not sure how you could use enough force to impress a penny's reverse on a half dollar without damaging the front of the half, but I also can't imagine how this level of damage could happen in the minting process (unless someone was careless with their loose change when the half was struck).

    Is it also gold-plated?
    Many of these bicentennial halves were.

    Maybe it's the brand of glue on his coin. ;)

    Definitely glue residue ... or remains of the 'gobsmack'.... Either way, acetone will cure the problem and not harm the coin. Cheers, RickO

    Interesting, acetone to clean it. I found a couple coin roll hunting that have goo on em. Ill try the acetone. These are just common date 1990 circulated coins, so i wont mess up anything valuable. Will be a learning experience.

    Glue will get you ever time. Along time ago I found a nickel that has a thin film of glue on it and had the same thing going on regarding the second impression of another coin.
    I was young and inexperienced enough to believe I had found the big one.
    A very simple/painful explanation followed.
