Both VAMs are listed as top-30 1878-S varieties based on the common reverse die. That fact could raise some interest in an AU details example but being both are known in grades up to MS64/ MS65 I doubt there would be much premium if any. This is just my guesstimate of course. If you would like a better idea I would suggest you join New VAMworld 2.0 and ask the value question in the buy/sell/trade section.
