Buckets are a tool, and one I use frequently. They're also worth $0. I see no reason for them to have a worth at all, and I accidentally sell mine a couple times a day. It's also the only reason I don't use /sell all. It would be nice if they were removed from the list of sellable items, and I see no way in which removing them would cause any ill effects: it would essentially be the same as now, only I'd be able to /sell all!
They should be worth .50, and they are in 3 different kits you could potentially use. Especially with /stack gone, I definitely disagree. We should be able to dispose of our excessive inventory of buckets with at least something in return. +1 /kit water +1 /kit pyro +3 /kit mobs (milk) I hate using disposal signs to remove things, and I don't always have one available. Unless of course I make one, dispose then remove the sign... which is just a waste of time to get rid of the extra buckets.
