The Burning Flames FR-0 resold for above sellers on marketplace, it's an outlier but it is what he received for this:

https://backpack.tf/item/1974747673

Sold for $159.99 on Mar. 16th

https://marketplace.tf/items/tf2/5021;6

Key price for the day is $1.90

$159.99 / $1.90 = 84.20k

I went and mini'd this properly, as this item DOES change our rounding. Our total would be 1927.2k, which would round up to 1950k, but given this would push us over a rounding threshold and add an extra 23k in value on top of the 16k it's already adding above unsolds, that would bring us 40k~ away from a more accurate valuation. Using the BF FR-0 open suggestion here instead: https://backpack.tf/suggestion/69e63d578d5c9c6f1d0be9cf

Taking 66k.

2x spelled non-Aussie sticky resold for 36k:

https://backpack.tf/profiles/76561198068640109#!/compare/1775865600/1775952000

Total for Aussie Sticky: 375 + 66 + 36 = 477k

For the Loch-n-Load we have a one-sided resale of 74k, nothing else moves in the day so clean enough to work with:

For the Scottish resistance, it resold for 130k:

Lastly, the bottle sold for 28k:

https://backpack.tf/profiles/76561198086355525#!/compare/1763769600/1764115200

Total for Sale 1: 750 + 450 + 477 + 74 + 130 + 28 = 1909k

No classifieds link, buyers are the same as previous suggestion at 337.5k, Bandai's unsold for 3000k for 19d isn't affecting this either.

One sale at 1909k. Rounding this to 1900k and taking that for the sole value.
