Re-suggest! Final one I promise, told different things.

Unpriced! 1 seller on bp @50k but the sale is outdated XD

https://backpack.tf/item/8459115139

Anyway, no sellers on marketplace.

2 in-date sales on marketplace -> https://marketplace.tf/items/tf2/31085;5;u8

May 21st @ 25.06 / 1.88 = 13.32k (~13k) - cant use as below b.o

July 9th @ 57.99 / 1.99 = 29.14k (~29k)

Seller on bp maybe asking for a bit too much here...

sale 4:

buyer: https://backpack.tf/profiles/76561197965601027#!/compare/1594339200/1596326400

seller: https://backpack.tf/profiles/76561198396190709#!/compare/1588377600/1590105600

Not sure about this: buyer shows it sold for cloud 9 hallmark(22 keys) + cloud 9 execution(17 keys), but seller shows it sold for 35 keys pure.

Both have a total value of 35 keys so I'll take that, but if anyone can help me out explain this to me that would be great.

value: 35 keys

Marketplace:

https://marketplace.tf/items/tf2/31085;5;u8

1x @ $25.06 / $1.88 = ~13.5 keys

1x @ $57.99 / $1.99 = ~29 keys

Summary: Ignoring the 13.5 key sale and rounding the first sale to 35 due to overpay in items, the range should be 29 as the 35 is Outdated.

Taking a price of 29k flat
