I think those 75MHz Apollo boards had a surface mount 68060LC on them, maybe on a small daughter board? It was impressive for some software alright, but many applications assumed an FPU was present when it detected the 68060 and promptly crashed when it tried to use it...
The late mask 68060s with a full FPU would probably be a better bet, and as such run to a higher price on eBay... But you never know, once it has "rare" in the title it's sure to sell for higher than it should ;-)
