I have built the worlds greatest collection of Unusual Hustler's Hallmarks - one of each type. It took months of work to locate them all and acquire them. The last was the flaming lantern, of which there is only one in existence.

I also endeavor to have one of every tradeable item in the game. I currently have one of every normal, strange (including all strange festive), and genuine item. I have most vintage items too (perhaps all, but I haven't verified this). I do have most non-tradeable achievement/promo items (I don't have any competition awards or that sort of thing - impossible to get them all anyway).

I currently have 51 unusuals in my collection, including the Hallmarks. I personally unboxed 6.

I quite possibly have the best, most complete TF2 item collection there is. Check out my pack and drool.
