Can’t find good mini for toy except for a 1:1 for a Miami Nights L'homme Burglerre which there’s a seller @ 13.37 which is too low when there’s buyers for warhood @ 12.5 Keys. There’s a seller at 16 for the toy so I’m gonna round down to 15 since there’s a lower sale that supports a lower price.

Taking 14 keys for warhood mini

28 + 8 + 14 + 29 + 35 + 8 + 1 = 123 keys

Rounding to 125 keys

Couldn’t find a B/O on tf2outpost of the seller so I’m not capping it

Sales we have are 55 and 125

Excluding 55 as there's a buyer @ 51k

Taking 125 keys flat
