Re-re-suggesting at a better range since a new sale occurred AND I accidentally made a mistake and screwed the range. That's what I get for making a suggestion at midnight.

My first attempt at pricing something that doesn't have a price yet. Hope I'll do good. Just so you know, this is for the Strange Haunted version of the item since Haunted-only versions don't exist.

Sold for 1 key:

http://www.tf2outpost.com/trade/23485310 Closed trade, no longer in bp and recently obtained a key.

Sold for 1.1 keys:

http://www.tf2outpost.com/trade/23428603 Someone offered 1 key and 1 ref, the seller accepted and the Pauldrons are no longer in his bp.

Sold for 1.2 keys:

http://www.tf2outpost.com/trade/23445652 Someone offered 1 Gift Wrap and 2 ref (~1.2 keys), the seller accepted and the trade is now closed.

Less than a page on Outpost, so if anyone can find more sales for this item, that will be great. Besides that, any additional proof, counter proof and constructive feedback is welcome.
