So I was going through a pile of Kennedys when something just didn't sound right. One of the coins, a 1971-D did NOT have the right metallic ring to it. Sounded a little more dull than it should (not the high pitched ping you'd expect). So I weighed it with a normal 1971-D and lo and behold, it was 1.7g lighter than normal (9.7 g as opposed to 11.4). When I went to take pics, I turned the two coins over and the reverse of the counterfeit(?) is heavily rotated from normal (not sure the term for that). So, is this a counterfeit (can't imagine why) or some sort of strange error?
Looks like a Magician's coin. Look at the reverse of the coin on the right. You can see where it was cut all around near the rim. I wouldn't be surprised if you could pop that off.
Bingo, that's what it is. Might take a little work to pop out but I bet the reverse has a British penny or Mexican coin on the other side.
I'm pretty sure it's this thing: http://spy-coins.com/MicroHalf.html Unfortunately I don't have the tool to open it. So, I can either try to sell for a profit or break it open and see what goodies are inside.
If it's a trick coin, you need a bang ring. Put the coin in the ring, bang it on the table, and it should pop apart. http://www.penguinmagic.com/p/S10659
Most likely there is nothing inside. I'd pop it open just for funsies. I highly doubt you will be able to make a profit. But then again, people are idiots.
Well it has the reverse of another coin inside at least. One I had trouble with, I clamped to a workbench and banged the edge at an angle with a hammer. The obverse piece eventually bent enough.
I think i messed it up initially by trying to push one edge in to get the other up... Now it's all stuck and I've shaken it a bunch with no luck
