There is no need to burn them, you just put them in a box and they are effectively off the market. If you examine the behavior of certain other thin markets, like art, this happens. The action of paying a record high price for something is because you own more of that item. It may happen with financial markets as well, but it requires a whole lot more money. My suggestion for any collectibles is first see if you can even find the item available on ebay, amazon, abebooks, etc. If its not, then that is a good sign. If there are a lot available and they aren't selling (watch the listing a week), then its worth a lot less than the asking prices.
