Sold for 25 keys. Could not find it listed on the bot.tf histories, so assumed it was not a quicksell + current buyers at that time were priced lower.

One sale on 23/3/2020 at USD 55 / 1.68 (Price of majority of the keys sold on that day) ~ 33 keys. (May be LuketheDemon's sale, not so sure, but its not there any more, so yeah.)

With that, sales at 25, 33. Pricing this at 25 -33 keys .
