For your first sale, the seller's b/o was 63 keys http://www.tf2outpost.com/trade/25883212. That sale would've been capped at 63 keys.

Looking at more sales.

http://www.tf2outpost.com/trade/26014007 b/o 65 keys Sold for GBH Hermes + Stormy Storm L'inspecteur + ~10 keys in Sweets. Should be capped at that.

Sales are commonly occuring in the region of 60+ keys. You only have a sale at 75 keys here which is potentially an outlier here. That being said, all the sales that i have provided here should be taken into account when forming a range for this hat.
