I can spot ‘em pretty quick...at least for the first 20 or so rolls..LOL. Then my eyes go glurky.
Yes, I agree, there are large numbers of 1980 pennies and some from the 70’s in unbelievable condition, for some reason. Mainly that one year, 1980. And yes, there are recent ones that look like corroded turds, just rotten.
I also notice that the 82’s and earlier have a significantly better strike. I usually pick out the clearly brown (good) ones that you can pick out almost immediately, then go back and just work off the depth of the strike on the date, without actually reading the date.
I just gather all the 1982s and weigh them later.
Nobody gonna get rich off this exercise, that’s a certainty.
The only blessing (for me) is that I have a super good coin counting machine, a Cummins Jetsort which I bought for no good reason except it was cheap, and it counts out the good and bad rolls pretty quickly.
It’s nice to live in an area where I can still take in a sack of pennies and they’ll count them for me. I weighed them first and the count was about right.
