$249.99 / $1.85 = 135.13 keys, rounded to 135.

Excluding this sale from the range because of an unsold at 130 for two months: https://gyazo.com/aa81aa425eba6054ea9c47820cd5839d

Phosphorous Modest Pile of Hat + Strange Chromatica California Cap + Strange Corona Australis for Strange Green Confetti Villain's Veil + Roboactive Cold Killer.

Going to consider this sale as bulk because we don't know how much the parties valued this hat at in their 2:3 trade.

Was used in bulk for a Gravelly Ghoul Patriot Peak. Trade looks like it was this hat + 7 various unusual taunts + Scorching Flames Head Hedge + Vicious Circle Berlin Brain Bowl + Professional Killstreak Festive Scattergun + 10 keys for the Gravelly Ghoul Patriot Peak. I'm sure this trade would come in handy pricing that hat, but it's all but useless here.

Bought for clean Orbiting Fire Blighted Beak + 25 keys.

The Beak is outdated.

Mini for Orbiting Fire Blighted Beak:

Using all in-date MPTF sales to get a range. Rounded to nearest 5 keys.

https://marketplace.tf/items/tf2/315;5;u33

October 16: $299.99 - $299.99 / $1.88 = 159.57 keys (160 keys)

November 7: $299.99 - $299.99 / $1.81 = 165.74 keys (165 keys)

November 24: $260.00 - $260 / $1.76 = 147.73 keys (150 keys)

Pricing the Beak at 150-165, or 157.5.

Because the duped Exquisite Rack sold for more than the pure, Blaze advised me to make a range using the clean sales too. This values the Exquisite Rack at 170-157.5+25 (182.5), or 176.25, rounded to 175.

This means the Veil sold at 175-63=112, rounded to 110 keys.
