1 march - 139 keys 22.11 refined rounding to 139 keys (My purchase)

According to ApothicЯ (Thank you for the suggestion), 2 trades for this hat 115 keys and 70 keys are invalid due to being dumped to bot

Tryaxis (the person from previous suggestion for this hat) stated they bought it for 115 keys (Invalid)

Probably got dumped to a bot since that’s where i purchased the hat from - 70 keys (Invalid)

Taking 100-139 as suggested by ApothicЯ.
