Mindacos mentioned that I should resuggest, it's only been 12 hours but that's enough time for me.

Literally just copy/pasting what he and Edrian wrote since I'm tired and conscious thought is hard right now.

Edrian's suggestion:

http://www.tf2outpost.com/trade/28538038 seller at 10 key bp.tf listing is 1 month old while outpost listing is 4 days old

Heres a 9 key b/o support

http://www.tf2outpost.com/trade/28417900 B/O is 9 key and is selling for 2 months and is bumped greatly

Mindacos's comment:

The crown is outdated. You should also be using that sale for the crown, not the other way around.

And I have to very strongly disagree with Salvage. 10 is not an outlier:

Sold for 10 Keys Pure

As seen here, the handle was sold for the keys, and the keys were immediately used to buy the little buddy.

Sold for 10 Keys Pure again

And a sale to support 9, don't use the crown sale for this please.

Sold for 9 Keys

http://backpack.tf/profiles/76561198291554347#!/compare/1470096000/1470182400

That makes it 3 sales at 10, 1 sale at 9 and a b/o at 9. Your previous suggestion at 9-10 was fine, resuggest at that.
