I just bought this 1 of 3 Bonzo Cotton Head for the keeps, i don't intend on selling it anytime soon.

Sold with 273 keys for a Demonflame Tough Stuff Muffs. Could be used to update the price of the Tough Stuff Muffs instead.

Sale 1 of the Danger is the only valid one i was able to find, so i am going with 70 keys.
