I tried ¯\_(ツ)_/¯

Resuggesting @70 flat as the Dapper trade was bulky.

Ether Trail Hellmet: Priced 2 months ago at 49 keys

Stormy Storm Napper's Respite: Mini at 16 keys

Victory Lap: Priced at 2.75 keys

Captain Cardbeard Cutthroat: Priced at 3.15 keys

Sweets: 2.55 + 3.22 + 24.88 + 3 + 6.94 + 8.06 = 48.65 ref or 1.5 keys in sweets

49 + 16 + 2.75 + 3.15 + 1.5 = 72.4 keys

Sale 2) Max's Severed Head + Searing plasma Baseball Bill's Sports Shine + Strange Salty Dog + Frostbite Pirate's Bandana + MW Top Shelf Minigun + 5 keys → Sunbeams Dr's Dapper Topper

https://backpack.tf/profiles/76561197996885192#!/compare/1521331200/1521590400

Max's Severed Head: Priced at 18.6

Strange Salty Dog: Priced at .8 keys

Frostbite Pirate's Bandana: 59

Sunbeams Dr's Dapper Topper: 150

MW Top Shelf Minigun: 4 keys

Would set it at 63 keys, but this trade is bulky

(That's what a mod said to do on my last suggestion. https://backpack.tf/suggestion/5ab73ffa44325a148f7618cd#comment-5ab8756444325a2bb43e21ce )
