I have a friend who has a passion for antiques. He made a middle-class income, but spent every spare dime on antiques. It was his passion. He'd buy antique SLOT MACHINES and restore them. Antique puppets. Antique posters. Old Tiffany Lamps. Furniture. You name it. He'd buy just anything he liked and could afford, and he had good taste. He eventually filled his house with antiques and had everything displayed with love and care. Spent 50 years doing it. Eventually he met the love of his life and wanted to retire and move to CA with her. A expressed interest to some of his connections that he was interested in selling and a company came and offered him million(S) for the house and everything in it. That was his sticking point. Everything must go. It didn't take long. He retired, married the new love of his life, and moved away to a beautiful home in a secluded area. He said that he did better collecting then he ever would have buying stocks based on the amount of money he was able to invest. Now I see on social media that he has been building up a collection of vintage JAZZ guitars over the last few years. I guess the bug never leaves you. What is the moral of the story? If you buy what you like (and have a modicum of taste), hold on to it for a length of time, you'll probably do well if you eventually sell. I think that can apply to any collectible.
