Collectibles.
Beer cans. It was quite a huge national fad in the 70's & 80's. I started when I was 10 in '77.
Must be from the 1930's through the 1970's, anything newer is undesirable.
Thousands of them displayed on shelves in my blacksmith shop because the wife won't tolerate them in the house.
I have other things in great numbers as well but I've never considered them to be collectible such as fishing lures, specifically for muskellunge fishing which I do use. I don't keep them displayed but they are organised in tackle boxes and tend to be antiques made of wood with glass eyes such as those who do intentionally collect them regard as valuable but I use mine so I don't think of it as collecting but I guess it is, isn't it?
Also lots of blacksmithing tools which I also use but a smith only really needs one anvil and I have six.
BTW, I am new here, hello to all. Dan.
DRAT ! !! I clicked on the wrong box, should have been "reply" not "new" and should be in the thread on collecting things by robh. Sorry I hope it can be moved.
