CopperWare

I am rethinking (Having second thoughts) my collecting. Is Copper Ware, Plates, Visions cook ware, Black Iron cookware, Glassware, Salt and Pepper Shakers, Cut glass, Carnival, Avon bottles, Books, Cameos, Hot Wheels, Match box 18 wheelers, Toys, Crystal limited Ed Print art, Thrift Store oil paintings and so on. Are these items really worth collecting? if so or not why? I hunt for Old or Antique Items but I really haven't fully learned how to spot them. I find it hard to identify all of it if not marked and even harder to find a Value for it. Have I become a Hoarder of junk that nobody wants or will not have value even after 100 years? Your input greatly needed.
