unusually thick 1968 us quarter

So it weighs in at exactly 5 grams

I'm sorry, but measurements from that scale aren't useful here. It's like trying to weigh out a quarter-ounce of material on your bathroom scale.

A normal-thickness clad quarter should weigh about 5.6-5.7 grams. If your coin is thicker, it almost has to weigh more than that. But we're looking for a weight accurate to at least a tenth of a gram, and preferably .01 gram. Your best bet might be a jeweler.

It would be interesting to weigh a near-uncirculated silver quarter (6.25 g) and see what your scale says. I'll bet it still says "5 g".

 

Do good and bad news. Did the ring text and the quarter split in two revealing a hollow rusted inner containing two small rectangular magnets. Very weak magnets. I'll have pics up tomorrow. Glad I finally know what it is...kinda... and upset it's not a mint error.

 

Thanks for following up! I'm sorry it wasn't a winner -- but, hey, at least it was interesting, right?

 

strange...

 

Undoubtedly a magician's coin, used for sleight-of-hand tricks.

 

has anyone seen a thick planchet error on the 2002 Louisianna Quarter? We have just found one double thickness to other state quarters. Bank coin machine turned it back to us when we took our change to be counted.

 

Any chance you could post a close-up photo of the coin's edge?

and a weight would like a lot also.
