I've been looking for the 82 small date the question I have since I'm on my jar of 3000 82 pennies I have 3 different kinds the 82 d large date the 82 small date but weighs 2.5 and 2.4 then I have the no mint mark that weighs 2.5 and 3.1 are the 3.1 with no mint worth anything than just a penny?
If it were MS it would have some value as it is a 1982 small date Philly copper. (The zinc 82-P SD is worth more.) But your coin is circulated, and I can't tell if that is a scratch or a light reflection. And both sides are needed to make any kind of examination. They made 17 billion cents that year, so even with the small date Philly (which is desired) condition is paramount.
It's a scratch the ones I'm going threw I'm putting on the side it's alot I do have some nice ones I'll post them later I have alot to go threw so will take me awhile hopefully but doubtful I'll find a true small date
