OP, do you feel like having lookies pawing through the various tool chests for days upon days as you try to sell tool by tool? Sort of an extended yard sale?
If not, and you want to dispose of all of them in one fell swoop, maybe you could consider consigning the entire lot to an auction house to dispose of all of it for you. If there's enough, a good auction house will pick all of it up, transport the stuff to their sales site, etc...no work on your part at all.
Of course, the downside is the seller's premium, or fee, typically around 20%, which means the auction house takes 20% off the top for their fee for selling the stuff for you.
But, I've seen guys go rather stupid at auctions for damned near anything tool related or if the item has a cord attached. Might be worth investigating as an avenue for disposal instead of trying to become yard sale man for weeks upon weeks, and still have random unwanted tools laying about with no takers.
