If I liked it, I'd keep it, but would not consider it an investment. In fact, I'd only hang on if I liked it enough that I would be willing to lose on it in the future because that's how I'd look at it. So unless I was in love with the thing it would go, and even more so if the money I would make could be reinvested into more stuff. For my Ebay I can spend more money on deals than I am fast enough to sell, so cash matters and it would be crazy for me to sit on gold or silver for a few years even if it went as as high as a 20% increase, because in the same time I can roll that money over for much MUCH more. That's how I've lived off $300 for the last 12 years... and even though gold has gone up, it hasn't gone up that much.
