I have six 1982 bronze pennies they all weigh 3-3.11 grams. Two with no mint mark and four with D. I'm pretty sure two of them have small dates. Are all or some of them rare?
All 4 of your 1982-D coins are Large Dates, which is common. Both Small date and Large date 1982 copper types are common as well. Sorry, No early retirement.
Here is a link to information on the large/small dates for the 1982 cents. This may help you. http://www.lincolncentresource.com/smalldates/1982.html
