Only 45 Keys match, buyout was 74 (https://gladiator.tf/listings/61f24e2f80fb42186f5f0b64), which would fit range anyways

Marketplace Sales

https://marketplace.tf/items/tf2/337;5;u36 - 149 on Nov 29 and 169.99 on Jan 17

https://manic.tf/keyprice/?at=2021-11-29&price=149

https://manic.tf/keyprice/?site=marketplace.tf&at=2022-01-17&price=169.99

$149 / $1.87 = 79.68 keys ~80

$169.99 / $1.83 = 92.89 keys ~93

Gonna say the sale for 93 was high given the lower seller on day of sale (https://gladiator.tf/listings/61e623745ccd6dd01bb00055) and the fact the most of the other sales don't even go past 80, and the marketplace buyer traded it away few days later

Going 70-80
