I'm a huge fan of crhing cents. There is so much fun stuff to look for. It takes me a couple of run throughs to get through a box, but after I'm done I usually always find several keepers.
First run through: seperate into 4 piles: zincolns, copper, 82s, wheats. I then 2x2 all the wheats and date when I pulled them.
Second run through: seperate 82s into copper and zinc (if possible I put together 7 coin sets)
Third run through: Copper sorting: There are 6 varieties I look for. If I find one I put it in a 2x2. I'll also pull pre 70 BU examples. After I'm done I dump all the remaining copper coins into a bucket.
Fourth run through: Zincolns... Till recently I didn't bother with these, but I've found I get a big kick out of em now. There are 18 varieties that I'm looking for. I generally always find at least one of the things I'm looking for. After I'm done I dump all these into another bucket.
After it's all said and done I return the bucket full of zincolns to the bank.
After the bucket of copper gets close to $50 in face I run an auction on ebay.
I generally save everything else.
I kind of need to start thinking about doing something else with the pulled wheats. When I first started 2x2ing them I did it because I thought they would be special... and they are... but... there are more out there in circulation than you'd think. I've pulled more than 2000 of these things out of boxes.
