Nice cards!!! I hesitate to venture a guess on the Jackson 10, but your best bet might be to contact the top few guys on the Bo Jackson PSA Registry and see what they think (i.e., offer).
VCP has just started tracking prices for 90 Donruss AQs, so there isn't a lot of pricing history for graded cards. Here's what's out there (last price in each case):
PSA 10s
190 Don Mattingly $1,248.23
201 Ozzie Smith $102.50
235 Darryl Strawberry $153.50
PSA 9s
166 Nolan Ryan $590.99
190 Don Mattingly $304.00
201 Ozzie Smith $118.73
BC-10 Ryne Sandberg $71.00
PSA 8s
1 Bo Jackson $89.00
33 Juan Gonzalez $201.00
61 Bo Jackson $159.92
184 Roger Clemens $68.57
190 Don Mattingly $102.50
223 Andre Dawson $36.00
230 Will Clark $515.05
235 Darryl Strawberry $89.99
270 Gregg Jefferies $50.00
BC-1 Bo Jackson $178.50
PSA 7s
190 Don Mattingly $133.09
You should also get in touch with the 1990 Donruss Aqueous Registry participants (cough) and have them make offers on any that would be upgrades for them. I'm sure one of them (cough) would be interested in a few of the cards.
