Heh. Back in Macworld Boston 1996, I bought one share of Apple stock at $16 and got a framed commemorative stock certificate. It went into a box when I moved later that year and I completely forgot about until I found it a couple of weeks ago. It's worth almost $1,000 now!

Unfortunately the state seized it as abandoned property (I moved a couple of times since and I never updated my address with the stock transfer agent) and I'm in the process of trying to reclaim the stock now. :(
