Ditto - I've been doing it for 50 years. Found some one-of-a-kind items. A lot of the really good items are just not available anymore. The best time to buy is during hard times which the Fed has prevented for the last 30 years. I've found mostly antiques (cash registers, general store items, furniture, soda fountain items, phonographs, clocks, oak wall phones, world globes, B&H lighting, model ships, books, 1920s Buddy L toys, classic sports cars, etc) and art at auctions, thrift stores, garage sales, and online sales. I look for unusual items selling at a discount. I've just collected a lot over the years and space becomes an issue, but it is an investment you can enjoy and small investments appreciate over the years. For this hobby, "let the bad times roll".
