I started buying signed first edition books in 2011. My excuse was that it's an investment, but really, it's a very bad way to invest. They're illiquid and they take up a lot of space. After finding MMM in 2013, I decided to sell my books. Finally after a year, I've breached the breakeven point. The books costed me $7000 and so far I've sold 80% of my collection for $7600. I'm glad to reclaim my closet and the time spent on Ebay. All proceeds went directly into the stock market. I'm still trying to sell off the rest, but did I mention they're illiquid?
