Ben,
If you want a quick and dirty checklist to get started (and don't already have one), just go to
www.Beckett.com and enter in "1910 Winston" on the search line (or "T209 Winston", etc). You don't need a member to get the list, but you'd have to pay for pricing (which IMHO isn't worth it for these specific cards). You can then take an old SCD (if you have one) and check based on player regarding scarcity. Not an exact science, but it might give you a relative idea of scarcity (though I wouldn't take either Beckett or SCD as gospel).
At least with a list of players it might make your searching a bit easier on ebay and auctions. Hope this helps!
