I hoping someone can help me with this because I'm not sure. I am going to send it to be graded I guess. I know only a few state quarters have been discovered on an experimental planchet and they are worth a lot of $$ so I hoping! Any opinions would be appreciated. I have plenty of pictures.
the rim looks like it has copper stripes, it's weird looking. I don't know if you can tell from the pic
With it being just a bit over weight for what a normal quarter should be I highly suspect that it is plated.
Honestly, I would wait before you go and get it graded. See if anyone else chimes in. Grading can get rather expensive and if it turns out to just be plated it will be quite a waste of money.
It's a plate job. The clue is the overweight that something was added to the coin after it left the Mint, which is usual for coins that get a plating of either gold or silver. I wouldn't submit it as you'll be wasting your money on the fees, shipping to and from, plus insurance. I see a lot of these at local coin shows and expos.
