There are a few issues with the suggestion and with the comment section, mainly regarding the current range.

- Opposed to what was said in the comment section, the DbD flamenco sale is not wrong and did not have that buyout, so you can take that at 65. The seller of that sale did not have an outpost trade at all.

- It was sale 2 that had the 50 key buyout http://www.tf2outpost.com/trade/28048326 ; that sale can be considered 50 because of that (which is not that much of a problem)

- Sale 3: I highly doubt the hard counter sale was 1:1; the seller dealt in cash and csgo as well, and asked less than half for his counter than for his escorter:

http://www.tf2outpost.com/trade/28048184 counter

usually when sellers take something that far below their BO, its either because they overvalued it (which isnt the case here seeing how the counter sold lower) or because cash or other stuff was added (which I assume here). If not, its probably an outlier.

- Sale 4: Sales of this nature should generally not be used to price a hat like this. A sale where multiple hats were traded for a hat that is far more valuable than both components of the trade should usually only be used to price the largest hat there. This would value the escorter at ~30% of the trade. Generally, when the hat you are trying to price is less than 50% of the total sale, the sale isnt suitable to price your hat.

Based on these sales I would personally put this at 50-65.
