My Wings of Vi background or if i pretend i didnt read the post, my statrak P250 Valence.

4€+

Gumiho the Nine Tailed Fox (Profile Background)

i guess that would be my weed emoticon (6-7€). ^^

You never said anything about unusual taunts not counting. ;)

As for the rest, without an easy way to look that up, I'd honestly have no idea and too many items to try to guess.

A deagle skin worth around $13 for csgo. Its worth more than I paid for the game.

The most expensive thing I currently have on inventory is valued at 0$ and is dust. How great is that? :D

*Actually I have a couple of cards that I don't remember of dropping... :\

A booster pack for a game called AR-K, a point-n-click game :p
