1982 Penny HELP !

@Hodge.... @TomB has summed it up nicely. If you are looking to fill an album, those coins are fine... If you are looking for high value coins to submit to a TPG, that is different... full red, unblemished surfaces, mint luster.... That will be much more difficult. Good luck... Cheers, RickO

Look at the sizes of the loops in the 8, the distance from 2 to the rim, or the length of the tail in the 9 to determine large vs. small date.

To determine copper vs. zinc, it's helpful to have a very accurate scale or you might have fun making a balance scale with a paper clip, thread and cut corners from an envelope to hold the coins. All Lincoln cents 1944-1981 are copper, and all from 1983-now are zinc, so you can compare to one of each of those.

As @Greenstang mentioned, none of the normal 7 varieties in your holder are very valuable, but the 8th variety not in your holder is the 1982-D copper small date, which is extremely rare and you are not likely to find even in hundreds of hours of searching.
