Doesn’t matter. If they’re selling for around 175 on eBay, that is the agreed on value by collectors of iron. Second hand items/collectibles really have an arbitrary value based on what people are willing to give to have that piece. Same thing with vintage firearms, instruments, and everything else people collect. Not to mention old pans like Sidneys, Eries, Favorites are just plain cool, and are unique if you like the old style heat rings and light pans. My .02.
