I buy complete truck D60s for anything from $50 to $100. Sometimes I can sell the drums and axles for $20-30, most times not and it goes in the scrap pile. If it's a locker rear I keep it intact, if it's open I save the ring and pinion if it's good and scrap the rest.
Bare housing I'd offer $50, but $100 is still a decent price. Make sure you look at the diff bearing saddles to see if it's been badly worn:
