How did this ever get so low?

Strange bubbling rotaion mini: http://www.tf2outpost.com/trade/27820555

Sold alongside 13 keys a 13 key unusual for a death by disco sombrero (67: https://backpack.tf/vote/id/56ed7314ba8d884339186347 )

67-13 = 54, capped at 50 b/o. Even if the unusual in question is outdated, it most likely is capped and/or rounds to 50. I can't check the histories.

My b/o for the hetman's was 50 as well. http://www.tf2outpost.com/trade/27967399

If someone could do the history thing for the mini that will be helpful, cuz I can't atm. The other recent sale was a 1:1 with a strange prof ks wrench, clearly an outlier. The rest are dupe sales.

Comments welcome.

there is a new open suggestion for the sombrero but it doesn't affect this https://backpack.tf/vote/id/56f16aafdea9e95443c42c51

Finally, here is the mini backpack compare link, definitely caps http://backpack.tf/profiles/76561198047620031/#!/compare/1455091200/1455177600
