Here is some information - 1982 Cents Mintage The 1982 Lincoln Cent was a transitional year in U.S. coinage, marking the shift from copper to zinc composition. The mintage figures for the 1982 Lincoln Cent are as follows: Copper: Over 10.7 billion coins minted in Philadelphia alone, with a total production exceeding 15 billion coins. Zinc: Approximately 7.3 billion coins minted, with a total production exceeding 15 billion coins. Your Cent is the third one on this list -
Mary your 82 small date copper is very close to having value. It looks to be XF condition and maybe AU. For this to have a little value you need it to be MS grade. The USA Coin Book lists it at $2.47 in MS 65. (Which seems high to me, these were always 50-80 cents in MS) I guess the price has gone up.
It has to be the 1982-D small date bronze (3.1g) to actually be "worth anything." Only two have ever been found and no one is ever going to find another one. I'd recommend buying lottery tickets instead. Finding all 7 varieties that can actually be found is fun though, did it a few years back and promptly spent them afterwards.
