hi david,
i vote for whole wheels. they are more likely to be put to use than parts, it seems a shame to waste the skill of the original builder, they are more likely to be an assemblage of period-correct spokes/rims/hubs, and additional shipping costs would be offset by the cost of spokes and the professional labor many buyers (or at least, i) would have to spend to have the parts reassembled into usable wheels. on the contrary, any time you save by not having to take them apart would be offset by having to find a lot of suitable boxes. good luck!
