I am contemplating eBaying the following:

Greyhawk 2nd print
Blackmoor 1st print
Eldritch Wizardry 1st print
Gods, Demi-Gods, & Heroes 1st print
Swords & Spells 1st print

Are the early prints likely to attract a much higher price?

I don't want to give them away.  But I have later prints in excellent condition which I am happy to keep.

Or maybe I should hang onto them to go with that elusive woodgrain I am going to find at a jumble sale.
