The reverse has been machined off. If the remaining coin is like a pie shell it was probably half of a magician's coin (two heads).
Larry, magician's coins are made by using a machinist's lathe to cut out the interior of one side (or the other) leaving the rim and cutting the rim and part of the opposite side of another coin away so that it will nest perfectly into the empty space created in the first coin. It could be a double-headed or double-tailed coin. Chris
No pie shell effect. Back side is flat and smooth. Thought it might be a magicians coin. The edge of coin is also smooth.
Same thickness as regular state quarter. Has no ridges on the edge. May need to let a coin dealer take a look. Thanks for everyone's input.
It has been machined as the cutting lines are visible, although a tight spiral used. If you show it to a dealer and he offers more than $5, take it is my advice. Welcome to the forum! Jim
It's a magicians coin as stated. Not sure how it being struck on a nickel planchet would have anything to do with a full obverse and missing reverse.
I have quite a few magicians quarters myself (amateur magician), and it looks pretty close to what I have. Knowing the minting process, it also doesn't really match up to any known error as well...so my conclusion is damaged/modified after strike. Your coin not having the same thickness of a quarter explains that it is part of a magicians coin...namely, it is the metal disk that fits inside the "shell" component.
I got one from my bank among my rolls. Got excited.same texture and same weight as the rest of my state coins. 5.7g. but has a thug when i drop it on the floor. Another guy has found one in the other forum. Surely this is not a magicians ploy. Its "p" mint. Guys, share me updates please., Thanks
