Let's try this again since I was told on the forums that the mini for the snaggle price isn't necessary as it's a minor part of the trade and I'm rounding down to be safe. I also couldn't find any recent sales of duped Scorching flames Ol' Snaggles anywhere, and believe me I looked:

Bought by me.

Sold for:

Burning stash (395 keys) + Ancient Eldritch Prehistoric Pull over (185 keys) + Scorching Flames Ol' Snaggletooth (55 keys this would need a mini though since it's duped, but since there are no recent sales of a duped version of this hat and I'm rounding down I'm leaving it as is unless someone else finds more evidence) + Dead prez Soldered Sensei (19 keys) + 150 keys=804 keys (rounded down to 800 keys).

Proof of Sale:

This shows all the keys/unusuals:

This one shows the hat is for sure the stormy 13th KE because if I did that with one photo it'd cover up all the keys:
