I have a lot of molds too, some are older & discontinued, but I get a lot of enjoyment from making tackle, and it's hard to put a price on that.
I don't have a Weedless Wally, although have been looking for one for quite a few years now. If they'll sell for that kind of prices, I can do without it. It would be cheaper to modify a regular Walleye Jig mold, or buy a CNC custom mold for the same style.
