97 pure.

Additional by Shuffle the Spy:

https://gladiator.tf/listings/614f136dc6d9885dadd18281 - Sale 1 had a buyout of 76 Keys, so I highly doubt it was 128

https://gladiator.tf/listings/61804365df9ee3171a47eb24 - Sale 4's gonna cap at the buyout of 91 Keys

91 to 97 would be a better range here, given the 76 sale sold in under a day.
