Antique is over 100 tears old. So I know they are called vintage. And I did see some sets on ebay like this one fir between 50 to 100 dollars.
Asking prices on ebay are not always necessarily the actual
selling price. For reasons I have never been able to understand, people have come to believe anything appearing "old" equates to "valuable", and that simply isn't the case in the real world: "rare and unusual" is "valuable". "Common as rocks" is "common as rocks".
On ebay: Click "advanced" (top right), enter brand name of product, scroll down and click "SOLD" and then go all the way down and click "newly listed" and then click "search".
To find the actual selling prices on items which were sold for a "best offer", you have to switch over to "Seller Hub" to get at that information - I cannot remember exactly how to get there, but I don't set my selling prices based on what other sellers are asking - that's a one-way road to ruin.
The ratcheting tap handle IS something that might tempt a prospective buyer if you don't put too outrageous a price on the set, which is going to have very limited market appeal with those thread sizes (the largest being 12-24.) A screw having 3-48 threads is something you'd find in a watch or on your glasses, maybe.
I'd see if it would fit into a medium flat-rate box ($18.40), pick a number, and post it on ebay "as is".
Just my two cents.
