Yeah k , But a mongolian seems a bit extreme, Isnt there an cancer hat with a higher tier effect or a low tier hat with a cancer effect?
Football Helmet, Hard Counter, Copper's Hard Top (Kind of cancer/low tier) and with effects G.Fetti/P.Fetti, Flies, Nuts'N'Bolts, Bubbles (Kind of low tier) and Peace Sign/Tf2 Logo (Low tier, would have to be with Mongolian). Most of these would probably go for more then a bill's though, unless you got really lucky and found a quickseller
 
something better? plox
don't get ahead of yourself.

peace sign and bubbles all go for over a bills, especially the hard top
 
Your offering like 11 keys. Not going to get much for that. Cheaper to sit on the shitty unusual.
