Searched some cents today. I didn't specifically buy rolls to search but my cent coffee can was overflowing, so I rolled a few. Looked at a bit over 800 cents and found:
183 copper and 600 zinc.
Two coppers were wheaties (1955 & 1958-D).
Out of 30 1982s (D and P), 28 were copper.
Found a couple of filled mint marks and the only other notable find was a very brassy looking zincoln - shown here next to a typical 1994. Caught my eye right away.
Weight, however, is right on target with the zincoln (2.46 gms). Maybe I will do a specific gravity test, but I think it is just a zincoln that, somehow, got a weird color.
