Well, they are worth one cent each! I assume you are wondering about the valuable 1982. That would be the 1982 D small date made of copper. You can google images to see the difference in date size, and weighing them will determine the composition. Your 1982 is a small date and your 1982 D is a large date. Don't get your hopes up of finding a D mint small date copper though, only two are known.
