I reached 3,200 rolls, or sixty-four boxes, in my 10,000 roll journey. The pennies are Canadian unless otherwise identified. Here are the stats for rolls 3,101-3,200:
* 1942 - 1977: 424, or 8.48%.
* 1978 - 1979: 130, or 2.60%.
* 1980 - 1981: 214, or 4.28%.
* 1982 - 1996: 1235, or 24.70%
* U.S. pre-'82: 149, or 2.98%. These are all non-wheat, non-'82 coppers.
* "Keepers," or semi-numismatic coppers that a naive or sentimental collector would keep: 16, or 0.32%. Six (6) of them are wheaties.
------------------------------------
Total coppers: 2168, or 43.36%.
I'm back on the fair side of luck, for now: the mean percentage of coppers for all my rolls so far is approximately 42.4%. I hope the fair side lasts, although I'm fairly sure it won't.
Another tracking category of interest:
* U.S. pennies, '82 and after: 350, or 7.00%. (I dump away all '82s, so I have zero '82 coppers.)
