There's only been 1 1982-D copper small date 3.1 grams that has surfaced. If you have the 2nd one, good luck to you.
There has been 1 small date 1982-D copper authenticated. Out of the mulILLIONS of small date 1982-D zinc cents minted, if you trust you scale and calibration techniques, pony up the $50+ and send it to PCGS or NGC. NO way to tell from pictures. Best of luck, but you are more likely to win the Lotto than to find a 1982-D small date on a copper planchet
