I saw he had it listed for 25, looks like it sold for 18.

https://backpack.tf/profiles/76561198349848918#!/compare/1724025600/1724112000

snap of classifieds at time of post

seller at 45 buyer at 16 and 15. no bot counters.

16,18,16 or 20, 8.5 or 20,15,15 or mix, and a possible 11. couple untrace.

With the two buyers at 15 and 16 im going to omit the 11. the 8.5 could have been a 20 and is also far below the couple buy orders.

the possible 20's are not confirmed but help to back up the 18 high point. multiple 15 sales and only one buyer at 16 so the 15 low side will work.

Big thank you to Mindacos for helping explain how the rules are used on the smaller ranges.
