As far as a monetary return goes the engine might not be worth rebuilding (if it needs it) but the parts are definately worth something.
The whole no oil broken con rod thing, someone might want to go to the trouble of buying it for just the rod.
The electrics you could test easily, i would be inclined to do it after id taken the head off and checked the bore and valve clearances, but if it spins ok by hand, there probably little harm in cranking it over. Just for the starter you could get $40 or more if it works.
Same for the coil.
