What's paper work worth, J-3 & PA-18A

[gator_av8r]

Does anyone have any idea what paper work is worth for a J-3 and a PA-18A.
The J-3 is N70777, log since new, currently registered to me, no data plate.
The PA-18A is N1871A, log since new, currently registered to me, has data plate.
Both of these were wrecked crop dusters from my father's air service.
