The keys do not show up in either comparison, as well it seems that the beak has been traded separately[§].

Valuing the Beak:

• Australium Medi Gun Prof.Ks = 38.51
• Crossbow Prof.Ks = 5.76
• Ubersaw Prof.Ks = 2.10
• Meet the Medic Infernal Flames = 36.5
• Spellbound Doctor's Sack = 48.5

Total Value = 131.37

Beak Value 1 = 368.63 (500 - 131.37)

Sale 2 (BUTTPLUNDER → ptrckr)

Beak Value 2 = 635

Final Price

Rounding both prices according to the rules we end up with a range of 370–640.

I'd rather price it at a flat 640 since it's the newer and highly clearer sale while the other one was a bulk cashout.

But I must not cherry pick and could not find any rule against large ranges like this.

If you have any remarks please let me know, thanks.
