I collect stones and rocks from different places. Also grass species from different areas for my herbarium. I'm embarrassed to say I also collect wooden cats and blue glass bottles (especially antique). Do I sound like a hoarder to you?
memories
I collect Sesame Street stuff (especially Elmo) and perfume bottles. But before I collect them, I collected old money (coins) from colonial era. So, I always got the coins from my grandma's vegetable garden everytime I play with my cousins in there. I left this hobby after my collections decreased little by little because of I barter them with my neighbor's candies -_-
Books, they are so heavy.
I've collected elephant figurines since before I knew I was doing it. I've got about 1200 of them!
I also have an informal coin collection; nothing too rare.
Hey, Comandante! Some of us will take umbrage with calling things from the 60's and 70's "old"!
In my opinion your hobby is perfect and very interesting. I envy you with "white and clear" jealousy that you have a time to do so interesting things.:-)
