Found this 2 headed 64 JFK roll searching this afternoon. Obviously, its a fake/magician's coin, but I have 2 questions regarding how this thing was made. 1. I can't find any seam on this coin at all. How did this get put together with no seam visibly showing? 2. This coin weighs exactly 12.50 Grams,the correct weight for a 64 90% silver JFK coin yet when I drop this coin on a counter it makes a thud sound just like any post 1970 CLAD JFK. WHY No "SILVER TING" sound whatsoever. It almost seems like its a slug, but the 2 sides have die scratches etc on them so I know they are from 2 real 64 JFKS! I thought maybe an air pocket, but then wouldn't that mean less weight and this coin is the exact weight of a U.S. 90% Silver Half Dollar which should mean both sides are butted against each other.  Also passes the tissue test- shows white! Any help is appreciated!      Edited by chuckster 125

I imagine that the lack of a silver TING is due to the same effect for crystal. When a piece of stemware is even imperceptibly cracked, it won't ruing when you flick it with your finger.
I imagine the same would be true for a joined coin. That they got the weight right is impressive.

You will find a seam on the inside of one of the rims, not on the reeded edge. The sound is dull because it two pieces fitted together and not a solid coin. This one is certainly interesting because it is 90% silver and exact weight, I would think the collectible value would be greater than the silver value.

If you look closely at the first pic. you can see a line near the rim
around 10:00 and 11:00 o'clock.
Also notice how close the edge of the date is to the rim compared to the second pic. Actually two coins are used to make one. A waste of good silver now, but the coin was probably made a while ago. Using either a machine lathe or a milling machine one coin is hollowed out
in a circular manner but not too deep as to cut through the other side.
Then another coin is cut and that section is dropped into the hollow
dish so to speak. In doing the machine work a few thousands of an inch
is lost near the edge of the rim. That is why the date looks like it is touching there on the 1st pic. And the line is showing part of the joint. Overall a pretty good machining job but not quite perfect. The adhesive used to join the 2 halfs together along with maybe some silver filling in the seam would account for the accurate weight.
This coin could of been by a homemade/work type job or from a large production run that made magician coins. I would tend to lean toward homemade because of the date/silver value. Most of the magic coins you find are clad ones.

Thank you both, for posting and for the info. That's a cool coin and you really can't lose with it...it's still worth melt either way, so you found what you were looking for, but its also one heck of a cool conversation piece. Gotta love that.

Borrowed educational images. They keep saying what they need to when questions come up. Thanks to "Still Lookin".

Did you open it up? You can hold the rim with the inserted side facing down and hit your palm on a table. The insert will drop off. I accidentally found two magician coins by the dull sound and it took a while for me to figure out how to open them up.
