Rare Mac game, where to sell?

[bmwcyclist]

I have a copy of Minotaur.

From what little info I can find, it is the first ancestor of Halo. (Minotar->Marathon->Halo)

Apparently, only about 2500 copies were made.

I don't see any past sales of it on eBay or elsewhere.

I need some $$ to fund my LISA projects, so I would like to find someone who collects this sort of thing.

Would Halo collectors be a better audience than Mac collectors??

All advice welcome.
