Bought it from Steam Market. No sell order on bp.tf just some buy orders looking for quickseller. Last price suggestion was 4 years ago!

Paid HK$ 569.27 (7.84 HK$ = 1 US$ peg rate) = US$ 72.61. Key priced at HK$ 18.32 (US$ 2.34) on SMC at that time https://imgur.com/a/mGh5Fx2

US$ 72.61 / 2.34 = 31.03 key.

Here's the item history of it: https://backpack.tf/item/565878312

Nearest previous owner seems just transfer the items to another account or maybe sold for cash and it's 2 years ago anyway: https://backpack.tf/profiles/76561198054762173#!/compare/1488499200/1498953600

Max. existed count of the same item was 5, and 3 of them were involved with someone marked as a scammer-exploiter to bp.tf with exact same time trading from and to a same user 6-7 months ago. So their trades at that time are invalid. Also they're now owned by collector.

The 5th one should be the Level 69 and don't think the owner would sell it at 31 key nor even selling it any time soon.

Thanks for the time reading and voting!

(Keys not seeing as US$ 1.8-2.0 plus 15% fee when buying at SMC is brutal....buying from SMC is really a collector's move for the Stout/Steel Shako I love 🤦🏻‍♂️)
