Sending it to a third party grading service will clear up any doubts about this coin.   |

Send it to ANACS for around $30.00 max you will get their opionon. Interesting coin, its strange that the metals detector puts it at 90% . At worst you will have an XF45 slabbed example of the one that might have been.

TPG may not even give an opinion due to ED.

If your dealer friend is a certified grader, he would have offer to send it in for you to get it authenticated.

I'm leaning towards a silver alloy cast copy, someone's idea of creating a "rarity" or the creation of a jeweler.
There is also a (highly remote) possibility that it was created by a Mint worker overstriking a 90% silver planchet that had been smoothed, but given the speed at which those machines operate, such a back room job would be extremely difficult to pull off for only a single coin.
The XRF machine would therefore be correct in reading 90% Ag.
The surfaces to me very much resemble those of cast coins.
If it were an off-metal or wrong planchet / foreign planchet, I would expect a different surface appearance. The US should not have had any 90% feedstock or blanks around in 1972 that could have made their way into the quarter presses.

 "I myself believe" this to be yes silver but a "sandcast" mold/molded coin by the appearance of the surfaces. Also note on the first pic from the bottom edge of the coin, about a third of the way up the edge looks to be were the two molds 1/2's were joined as the line runs (from what the pic shows) consistently around the circumference of coins edge...the whole way? and the reedings ("denticles"?) all of them do not look to line up perfectly. |

Weight is correct (within tolerance) for a copper nickel clad quarter.
Since an XRF gun has a limited penetration if the piece is plated with pure silver the gun is going to read mostly silver and most of what would get picked up from the subsurface would be copper So I could believe a 90% silver reading on a plated piece. The key is what was the other 10%? All copper, or was there also nickel as well?

There was indeed a 1972 silver quarter posted on this exact forum years ago. It was struck over an actual 1964 silver quarter, already struck, probably made by a rogue employee. No one believed it but it turned out to be genuine and got NGC slabbed. This doesn't look like it was struck over an already struck coin, but considering we know a 1972 silver quarter exists now I'm not gonna call it impossible. This one looks cast or pitted at best though. No idea why one would fake a 1972 quarter, so it could also be a bad plating job. Interested to see where this goes though.

Just because the dealer has been in business for over 30 years doesn't mean he is an expert in the error field. The vast majority are not. I am certain this coin is fake, either plated or cast. The surfaces looks corroded. The XRF gun is really only reliable for surface metal. You can send in to a grading service but you will be wasting your money. But if that is what it takes to satisfy you, I am all for it. If there is a larger coin show in your area, take it there and seek out a dealer that specializes in errors for your best advice.

Looks like a cast as mentioned. I wouldn't waste your money on getting it graded.
Errers and Varietys.

If you don't want to send it to a TPG without being really sure run a specific gravity test on it. The SG of copper nickel clad and 90% silver are different enough that you should be able to tell. |
