9-10k, 9.5k.]

All recent sales on the nuts bandana are bulk https://backpack.tf/item/5106663376, so I'll just take buy order values here at ~8k https://backpack.tf/classifieds?item=Burning%20Bandana&quality=5&tradable=1&craftable=1&australium=-1&particle=31&killstreak_tier=0.

117.5 + 25.5 + 15 + 9.5 + 9.5 + 8 = 185k}

185 + 210 + 78 + 49 + 20 = 542k
