Weigh it on a scale that is accurate to 0.1 grams. Both brass and copper plated zinc cents were minted in 1982 so if it weighs 3.1 grams, then you just have a plated brass cent. If it weighs 2.5 grams, then it might not have the copper plating or it could have a post-mint plating job. Post-mint plated coins usually have tell-tale signs that can be seen but your pics are too pixellated to visually tell what is going on.
