Updating 4 months old price. Only 6 such hats exist, just 1 active trade on OP, none in classifieds, on bazaar, tf2wh or tf2shop. Since in at least last four months there have been only one seller, the range is based mostly on buyer's willingness to pay. Increasing the low value to 18 keys since, considering the consistently low supply, too many willing buyers for 17 keys. Increasing the high value as there have been willing buyers at 22 keys and 1 bud. Since the bud offer was made just a few days ago, when buds were already known to keep falling (already selling for 22-23 keys), setting the high value at 22 keys.
