I'd guess many coin collectors got their start being patient enough to sort through change to see if they had e.g. a wheat cent or silver dime, but first of all, who pays with cash and gets change, and the chances of finding something collectible are orders of magnitude smaller than, say, the '90s. And stamp collectors would have started saving the stamps on mail sent to their house, but how frequently do you get stamped mail anymore?
My 79-year old father goes to stamp shows, because one of his hobbies is to buy sheets of old but common unused stamps for less than face value. They are still valid postage, and then he uses them to personalize the stamps he puts on letters he sends to various people. And most of the other people at stamp shows are about his age. He does have some stamps he thinks are interesting that he's held onto, but the dealers at the stamp shows think they're common and uninteresting. So there's a decreasing number of stamps that might be "worth something" and a net loss of collectors in the hobby, and then every time a collector dies and his heirs have no interest in his collection and that many more stamps make their way to dealers who now have one less buyer.
Too bad "sending paper letters with vintage but still valid stamps" never caught on with the hipsters.
