Some semi-keys/keys I would focus on due to low mintage, and some softening in the market allows for bargains to be had:
1924-S
Buffalo nickel1931-S
Buffalo nickel1921 P & D
Mercury dime1996-W FDR dime (mint set only)
1970D; 1987 P & D JFK half (mint set only)
1973 P & D
Ike dollars (mint set only)
All CC Morgans, especially higher grade
Some teen mint marked wheats, especially 11-S
38 D & S, 39D & S, 42D, and 50D
Jefferson nickelsSome of the lower mintage
Franklin halves could be sleepers
38D
Walking Liberty halfI think some of the keys are are bit overpriced, like the 16D dime, 09S VDB and 14D cent, so this is why I'd focus on some of the semi-keys, which have a lot of upside potential- not sure which ones would take off, but of the above, some of them are so cheap, you almost can't lose!
I agree also with lower mintage Barbers, though it depends on whether there will be an increase in collector interest in those series to help drive up prices.
