Realistically, anything you buy depreciates with time. The popularity of what you own can make the price increase due to the rareness (in this case) of a pin in question. I'm with many here that for me, its a hobby. I have no plan to sell unless I may be living out of a cardboard box (a Stern one, *rimshot*) but I am with many others in saying, if you're in it just for an investment, there's better things to invest in. I'm gonna have fun and fix it up when it needs it and have more fun. That's the life of someone who enjoys a hobby.
