But not every item is available in the store. The ones that aren't - unusual hats, super-rare "glitch" items, community weapons - sell for hundreds and hundreds of dollars.

One such "glitch" is known as a "vintage scrap metal" which only a few exist in the game. They popped up when a user would delete their metal and ask valve to put it back, when they did, it showed up as "vintage scrap metal" with blue text. Such metal has sold for over $1,000.

I feel much of the TF2 economy (these items that can't be bought in a store) is simply players holding onto the weapons and working together to sky-rocket the price. Now, people refer to a "spreadsheet" which is set by a group of individuals. Everyone follows this spreadsheet religiously.

For small items, I think the TF2 economy is very neat. But for rare items? A mess.
