Problem is it's one needle in a giant haystack of millions of mass produced craps. You never gonna figure out what is valuable in the ocean of turd unless you have years of experience in this domain.

I'll give you a lil tip for noobs anyone can apply tho : Uranium glass (yup was popular in the 20/30s to put uranium in glasses to give it a green taint lol) always sell for good money and isn't too hard to find, so if you scout for good deals in antique shops or flea markets, remember to fit an UV-lamp in your pocket, UVs react very violently to uranium, it glows like crazy you can't miss it.
