How much are they worth?

[Southtowns27]

Hey guys, need some input. I have some old taps that I would like to sell, but I don't have any idea what I should ask for them. I have 400+ cast spiles with a Patent date of 1884 on them. They're an open style, not a closed tube that the sap drips out of. They're in near perfect condition, with the hooks.
Second, I have some of the sheetmetal style that you use a "spile driver" on to put them in the tree. Also in VG condition with hooks.
So what should I ask for them?

Try looking on eBay for similar spouts and see what they're going for. I've got some of those old open top ones - just for my collection is all. The rolled tin Grimm style are still popular and widely used, and I've seen them listed locally for $1.25 each.
