Statistical Finds From Lincoln Cent Rolls

I didn't see a thread close to this even when performing a search, so I figured I would start a thread that calculates what I have found upon searching through Lincoln Cent rolls from the bank. Today, I picked up two rolls and was surprised they were in paper versus the plastic they almost always come in. I wonder if that means these were customer wrapped rolls. Anyhow:

Canadian cent from 1976


From the first roll, I ended up with 16 coppers for 32 percent. Only five pennies in the roll were from 2000 or later which I found odd. The second roll had fifty-one cents there was a Canadian cent that was a bonus so-to-speak. For the second roll, I had 13 coppers for 26 percent. Still no cents past 2000 in the second roll. Someone must have a thing for post-2000 cents.
