Nice rotation! This is the second coin shown on CoinTalk today with a 90 degree. The Reverse is a Misaligned Die Strike. So you have a Major and a Minor error together! Thanks for sharing
I just thought of something though... maybe it could be a Magicians Coin The Obverse is the shell and the Reverse is the insert. Try dropping it on a hard surface to see if it pops out! There is a magic trick called Scotch and soda. The Outer part is the shell and the inner part is called the plug. Looks like this. Mexican coin on the other side.
What does the reeding on this coin look like? I ask Because it looks like it may have been machined and put together. The edge of the reverse could be some sort of crimp.
Okay, took it out of the holder and dropped it 3 times on edge. Nothing. Here are a few more close ups of the edge.
That was my first thought when I saw how separated the rim looked on the reverse. A sharp knife should pry that reverse out. I've never seen a Kennedy rotated out of tolerance, much less a 90.
A scotch and soda set will sound very different than a regular half. The easiest way to take them apart is shaking it in a glass. (Yeah magic is my other hobby)
If it has been machined and crimped it will not come apart. If there is three marks on the reeding 120 degrees apart, that would be a sign that it was chucked into a machine lathe to hollow out the reverse. It could also have been done by gluing to a spindle and then remove the glue. the reverse would surely has been done with a glued spindle. Can you check the weight to see if may be different?
It weighs 10.9 g compared to others I have ranging from 11.0 to 11.3 g. It also does not have the 'ting' when dropped flat like a normal coin. DANG! I thought I had something good. Thanks all for the comments and help with this. Anybody want a Magician's coin?
It would be cool to have one of those. Recently a magicians coin was used on a Network TV show called Designated Survivor. It was used by a CIA analyst who snuck a very small flash drive out of the secure area. It was in the form of a quarter though. Pretty cool to have seen it on TV. The name of the episode was "A traitor among us".
My wife and I like this show. I actually did see that episode and thought that having a coin like that would be cool. Now, just to open this one and see if it has a chip inside!
Someone mentioned before to put it in a bottle and shake it. Try a glass jar. Rattle it around a bit until both the cover and plug separate. Unless it's glued.
yeah, what paddyman said. I did this before with a cardboard box (couldn't find a glass jar... d'oh!). It took a while shaking it in a circular motion. I soaked it in acetone, too because mine was glued together for some unknown reason.
Google "bang ring." I got an aluminum one on ebay a few years ago for 1.25, but I see now they are more expensive than that. It is a device specifically made to get these apart. I had one stubborn enough that no matter the shaking in the glass, it would not come apart. These magician coins are also also known with old Brit pennies. I found a total of 10 of these coins roll searching over the years.
