I don't play TF2 but I had a crate key in my inventory. It sold within 30 seconds of me listing it for $1.61. It looks like it is limited to TF2 items right now. A quick way to add some funds to your Steam wallet if you have stuff you don't need.
I receive Steam beta updates so it may not show up for you if you don't.
