Hi all, so I was going through some coins and weighing my 1982 d pennies and I just started putting other things in the scale out of curiosity. Well I came to a 1991 quarter that weighs 5.79 grams. I have a ton of coins cause I'm a bartender but I'm still pretty new to the coin game. To me it doesn't look any different. But as far as I know it's not supposed to weigh this much is it?

Hi guys sorry it took so long that photo uploader was kicking my butt. I finally just found an old editor I had. Lol. So it is probably within the standard accepted weight then? And I can go play some pinball with it? Lol

Pretty sure that the tolerance is +/- 0.19 g so yes your quarter is on the heavy side, but within specs.
Also, welcome to CCF!

Quote:@conder, it would seem that both 0.19 and 0.227 has been described in the past here and elsewhere on the interwebs as the Weight Tolerance on clad quarters. I'm not sure which one is correct Halo has the correct tolerances posted, you will see the clad is .227 +/- To add another bit of information, you note the .194 for the 90 % silver is for 1947 to 1964. Before 1947, back to 1873, the tolerance was +/- .097 grams. Before 1873 it was +/- .065 grams. |
