So, I just got a gram scale the other day, and so I'm weighing some of my copper pennies. The lowest weight so far is 2.95, which is off by 0.16 grams. The mint preferances for +/- is 0.13. So that's 0.03 grams off the normal weight. I don't have a weight higher than 3.26, so no errors there. But I want to know, is there a price guide for this?
Well, I'm not talking about my coins. I figured as much as far as selling price. I mean for if I find one that is way off the tolerances. Like a copper penny weighing 3.8 grams. Is there even a price for these? Or is it just whatever someone will pay for it?
