"Lowball" (Dollar) Coins: How to know which are worth submitting?

I'd appreciate comments/advice from anyone with experience in the field of 'lowball' coins.
Are they best perhaps just sold on BST (or ebay,) without cert'ing?
Is there any other way to guage which ones are likely to be subject to demand, or is checking the Pop-Report for low #'s ('supply',) and guesstimating likely demand, the only way(?)
Supply AND demand info would naturally be best, but the only thing I can think of is the "supply side", using the Pop-Report.
If this adds anything, at the moment I've got...
Morgan: 1884-P, 1890-S, 1901-O
Peace: 1922-S, 1923-S, 1935-S (35-S (approx AG3) Looks like maybe the best, but I don't know level of demand.)
TIA

there are only a few strong lowball buyers - but a new low can command MS63 prices from some buyers, if it adds to their set
PCGS slab helps because of the closeness of PO-01 and F-02
and the problem coins that will not slab
