Just updating, seems like there are 2 sales here.

Sold with Frostbite Kabuto + 6 keys for AF Scopers + Snowfallen Missing Piece (37 keys)

Without an available mini for the Kabuto, this sale should not be used.

While the Missing Piece is indate, the Kabuto has no recent sales, and the Scoper's only has 1 recent sale, and I personally believe it is low:

Sold for 38 keys

Sold for 175 on April 18 (175/1.79 = 97.77 rounding to 98 keys)

And it also seems like a new seller has arrived @ 75 keys.

98 seems like an outlier, considering the current sellers at far lower.
