Collecting stuff is an interesting hobby. My mom and dad sold antiques. They always told their customers to collect something that they liked. That way if the value of what you were collecting came down you still had something that you liked.  Too many people bought stuff as investments and were ticked off when it lost value, (beany babies, ertl toys, collector plates, ) the list goes on. If you are happy with your collection it is priceless. It's great to find things that are less than going prices. But that is no guarantee the value will go up.
