When you search nickel rolls do you loupe every coin for errors or toss some dates / mints straight back and only set aside certain years for closer scrutiny? If so which years and mints do you look at?
You could pick up a cherry pickers guide book and pull known variety dates to the side or give all the coins a good look in hope to discover a new variety. It depends on how much time you have to devote. Have fun!
When roll searching I divide them up by dates and mintmarks. Toss the newer ones into bins and sort those quickly under a loupe looking die cracks, die chips etc. Then I search the known RPM/DDO/DDr under a loupe.
i keep ever5y thing before 1960 and most of the ones upto 1990 with full steps. i look at all that aren't marked up with a 12x then trade them back in.
I have a list of nickels that I keep an eye out for, but I look at every coin just at as close as I would look at these. 38 Low Mintage 39 Low Mintage and 39 double die reverse 41 D&S Large S, Inverted S Mintmark 42 P&D 42 Double die Obverse, 42 D RPM D/Horizontal D 46 D&S 46 D RPM D/Horizontat D, 46 S D/D obverse 49 D OMM D over S 50 D Low Mintage 54 D&S 54 D Double Die Reverse, 54 S OMM S over D, 54 S RPM 55 D OMM D over S 56 D Double Die Reverse 59 D Double Die Reverse 62 D Double Die Reverse 64 D RPM and Double Die Reverse 2004 P Double Die Obverse
