I mean, "No intention to sell" was partially true, given I bought the thing back in the end.

Even though I updated this only a couple months ago, it's current price isn't indicative. Also dropping my own hat, but I don't care.

Sale 1)

https://backpack.tf/profiles/76561198259986634#!/compare/1549497600/1549584000

Sold with 12 keys and a Rockets Touchdown for a Strange Batsaber, in-date @ 42.

Taking lowest seller on the Touchdown, 3.4 keys, given it's only four ref above buyers and there's multiple sellers in that price region, rounding down to 3. 42-15=27 keys.

Sale 2)

https://scrap.tf/auctions/C0BRNR

Sold for a Circling Peace Sign Dread Hiding Hood through Scrap auctions; excluding, as the sale only happened from exploiting the auction system, and is not indicative of it's value.

(For context as to what I mean, reference this thread https://forums.backpack.tf/topic/70130-did-i-just-get-scammed-through-an-auction/?tab=comments#comment-619080 )

Sale 3)

-------------------------------------------------------------

In-date sales;

42,33,33 and 27.

Even though 42 is in-date, calling it high due to several sales below it and a current seller @ 35.

Still somewhat new to suggestions, so if I've done anything wrong here please let me know.

Also, screenshot of the seller, in case it sells or is taken down.
