What's chic these days, and in, is anything that people want, will pay money for, and can't find readily. In other words, if they don't make it anymore, chances are someone is looking for it, collecting it and wanting more.
Collectors invest considerable time, money and effort in their collections.
Consider them speculators - betting on the value of pieces of furniture or glass instead of the future commodities market. You can collect virtually anything - cookie jars, oak furniture, mirrors, clocks, tea cups, train sets, Barbie dolls, baseball cards, oriental vases, country quilts, Depression Era glassware, fine china, cat or dog figurines, Mickey Mouse or Disney paraphernalia, sterling silver, clocks, watches, the list is endless. If you like it, then learn everything you can about it. Collecting is that much more fun when you search for hours for just the right piece - and get it at a steal because no one knows what a value they're sitting on. Once you decide what to collect, then you figure out how.
