Rotated Reverse

to CCF Wendy. That's a nice find. It is for sure collectible. Don't clean it, that would lower the value. We will have to wait for a pro to chime in on this.

Hello, and welcome to the forum!

If genuine, this is a valuable error and is very collectible. That is a big IF, however. I've found several altered Kennedy half dollars with rotated reverse. These are "sandwiches" made from two coins by hollowing out one side of one half dollar, then grinding down the edges and one face of the other coin to fit it into the first, hollowed-out coin. Such fakes are usually easy to detect:

1. Closely inspect both sides of the coin along the rim. A fake will likely have a thin groove or seam all the way around one rim.
2. Check the weight. A normal 1971-D Kennedy will weigh 11.34 grams. Fakes usually are much lighter.
3. Drop the coin onto a tile counter and listen to the sound. A fake will usually produce a dull thudding sound. A normal coin (or a genuine rotated-die piece) will give a clear ringing sound. The difference will be very obvious.

Don't get too excited about your find until you have performed these tests. If the coin passes, it would be worth paying a grading service like ANACS to certify your error coin. Good luck!

well it didn't exactly pass ANY of the tests. HOWEVER it is my first fake coin, so it's still my first something :D and figuring it out was 1/2 the fun of the hunt - plus I learned how to tell a fake from genuine. I am still pretty excited lol. It will take more then a fake find to burst my bubble.
I am going to start a book of all my fake finds.
Thank you for the help it, it was extremely enlightening.

(I can't believe people take the time to actually do that though!)

I had heard that also so when I found my first altered Kennedy I attempted to make it separate, with no success. I even tried boiling it in water to pop the two sides apart. I eventually found four similar coins from roll searching. These have various rotation values from 90° to 270° and none of them open up. I also found one 2-headed Kennedy and another with two tails, made using the same sandwich technique. Perhaps there is a crazed half dollar alteration specialist in my area.

I'm curious as to the tests you did on the coin.
What was the exact weight ?
Did you see a seam anywhere and if so
where was it located ?
I can see a Magicians coin heads/heads etc.
but why bother with just a rotation if wanting
to alter it. Anything over 90 degrees is collectible.
Yours seems to be in the 100 to 105 range.
Just wanted you to be sure that it is indeed an altered
coin and not the real deal.

I still cant believe it. I am sure now that it is a trick coin. I can not really see a seam, but I think there is one at the rim. And it thuds on the tile as well as the weight was about .08 lower then it should be. But I do not recall the exact weight that it was.
its all good though, I already found another rotated reverse coin. lol. It is just a penny so I REALLY hope it is real. :)i think I will take a picture and post it later.
I found an AMAZING coin shop about 30 minutes from where I live, so now I am really excited about collecting.
Any advice on what my first buy should be?

soooo.... no chance the mint made coins that open by accident, huh?
lol - guess I found a Houdini
