I recently found a 1971 Kennedy while searching with a 90 degree die rotation. Where should I send this piece for certification and a guess on it's approximate worth.
may be a magicians coin where the 2 halves come apart. If it makes a hollow sound when dropped, that what it is.
Contact the people at rotateddies.com. They can add it to their list and help you with rarity and value.
Drop the coin on a table. Listen to the sound. It will go "THUD" like a chunk of lead. It will probably not ring like a normal half. Although you can't see the seam because the coin has circulated, the coin likely will come apart and is a Magician's coin. I have looked through literally millions of half dollars and any that I've discovered with rotation have indeed been Magician's coins. Don't waste your time sending it anywhere if it goes "THUD" Thanks, Bill
The point is not that it is rotated. When the thing is not beat up and circulated, it is a multi-part piece made out of several coins and manipulating the parts can cause the thing to have two heads or two tails. I posted a picture recently of a half that had a quarter and a dime machined and tucked away inside. Others have an insert in a shell that can be flipped, making the coin appear to be a British penny or an older Mexican 20 centavo coin. The appearance of a rotated die comes when the person who uses it as a part of a coin trick pays no attention to how he puts the parts back together. Thanks, Bill
