And the ur-example is baseball cards. My dad's childhood collection was worth something like $40K in the 90s. He literally bought about 800 of them over 3-4 years in the mid-late 50s, then not only lost interest in them but in baseball completely, and the cards sat in the same clean, dry, temperature-controlled basement for 40 years until they became lottery tickets. What everyone needs to do is to take that hobby when you bought a lot of rare, fragile stuff, and publish a high-priced coffee table book about it. Some rich bore will use that book and his money to simulate a personality, and other jealous idiots will try to imitate him, bidding up the prices.
