Three bucks a board foot for 48" wide, 10/4 black walnut is an absolute steal. Slabs like this often times sell for 5X that amount or greater.
Even if they are green, grab them and stack / sticker them where they can dry.
Black Walnut is a very forgiving wood to air dry, and as others have stated if you do the initial drying by air you may end up with a more robust color.
From green, if exposed to reasonable air flow 10/4 BW should be down to 15% MC or thereabouts in 16 months or so (depending upon the time of year when they are milled). From there, you can finish them off in a kiln.
I would suggest that you avoid any slabs that were cut through the exact center of the log; it's better to be one or two slabs away from center from a drying perspective.
As far as determining the MC% w/o a meter, if the slabs are consistent enough in thickness you can weigh them and then calculate the volume of the slab to determine the weight per bd ft.
Green BW weighs around 5.27 lbs/bd ft, and that is based upon 85% MC. Dry it will be close to 3 lbs bd ft. A loss of 29 lbs of weight represents a 1% MC reduction.
