Many people don't realize their collection of old power tools left over from a family member's bygone days of shop work can actually be worth a bit of money. A quick check of sites such as Craigslist or your local newspaper's online classifieds will reveal many people selling antique power tools. Antique tool enthusiasts lament the fact that most people simply discarded their old tools rather than hanging on to them. Today, eBay auctions, flea markets, and good old-fashioned auctions are all places you can buy and sell antique power tools. Don't simply throw those old tools away, you could finance your next tool purchase with the proceeds of an auction or sale of the old stuff that you have stashed along the back wall of the shop.
