I did find all years/mintmarks from 1965-2005 (no '06's) but no silver, S-mints, 1982 no-P, or 1996-W. Not sure if I'll go thru another box any time soon. Depends on when halves pick up again.
I tried two boxes of dimes in the past and I found no keepers. I didn't enjoy looking thru them either,so I don't search them any more. "I feel your pain." hehee
I don't understand how any of you keep your sanity looking through dates on pennies or dimes, haha. I just check the backs of pennies for some fresh crops growing or the silver reeded edges of the dimes.
Although I do check dates for nickels because that is the only way to get results on them and they are a bit bigger....
