Having trouble with the small and large dates!! I have 6 brass 1982 pennies. Two of them no mint marks and four with D. They all weigh between 3 and 3.11 grams. Can someone please help
Perhaps you should look into what the mint's tolerances were for said type. Between this and any circulation wear/damage, it may very well explain what you're seeing. And welcome to the forum.
Only if you actually have one. You need to provide pictures! http://www.lincolncentresource.com/smalldates/1982.html
3.08 does not equal 3.8 Also, it's a large date. They made 17 billion cents in 1982. It's worth .01 cents.
