16 keys + Holstered Heaters (~2 keys) + some low tier craft hats match via IDs:

Buyout was 15 keys 28 ref https://gladiator.tf/listings/608f7e94461d1e7fec935006

Even though the IDs for the hats match they don't match via histories. I'll just take as 16 since the hats most likely went to something else
