It can not be a mint error, there is no way a smaller planchet can be struck by quarter dies and still show the reeding on the edge. The reeds are struck at the same time as the face and are in a closed collar, the collar is on the outside of the dies. A smaller planchet struck by quarter dies can not show the reeding on the edge, just can not happen that way.

Probably done by a machinist who was on his lunch hour.

Looks milled because the images appear to be normal sized but because it has ridges also could be slightly...shrunk.
Kind of a hobby for science nerds.

Interesting find. If your coin is in fact an error, it would be a "wrong planchet error." From the pictures it appears it would have been a "quarter struck on dime planchet" error more specifically. Here is a quick test for you: Is the coin the same thickness as a dime? A dime is 1.35mm and a quarter is 1.75mm. Now it may be thinner than the dime, but if it is over say 1.40mm I would say no chance it is real. The other thing is, I doubt that the entire edge would be reeded if its real. The reeded edge is obtained during the striking process. The collar in which the coin is struck contains grooves that, once the die applies pressure to the planchet, leave the reeded edge. Now, if you imagine a dime in a quarter-sized collar, I doubt that all of the reeds would imprint 360 degrees around the entire planchet. Let us know what you find. If it's the same thickness as a quarter, it's more than likely not a real error. If in doubt at all though, take it to an expert. Without holding and seeing the coin personally, it's very difficult to ascertain much.

Its probably just a strange mint error.

Looks like the center of a silver quarter that's left when you punch it to make a coin ring. I think someone added the reeding for fun.

 

[Jason in Enid]

definitely NOT a mint error strike.

RobRieman beat me to it. This is the circular piece cut out of the center of a coin ring-in-the-making by a jewelers saw in my very humble opinion. Sub

Absolutely no chance of it being a mint error.

Easy to put it in the lathe, turn it down, then add ridges.

Why, well, that is a different story.

 

[saltednuts]

this is easy to settle show it to an honest expert like third party graders at any coin show i never said i garantee it to be a mint error just voiced my opinion

I briefly got into rolling rings from coins. Can make a ring from a quarter for a lady or child. The first step is to punch the center out of the quarter. The piece you found is the punched toss away part.
