Two more sales happened since my last suggestion. One of the nobles seems to be sharked, but I talked to the old owner, and they seemed to not care for how much they sold it for.

He bought for 2 buds pure(Outlier)

He sold for Duped Burning Buckaroos(~2.8)+Strange Gunslinger(~1.4)+Strange PDA(~.4)+Strange Invisawatch(~.2) = 4.8*.9 = ~4.3 buds

The high range comes from my original suggestion:

Feel free to give feedback on this suggestion. I am not sure I was pricing the buckaroos correctly, due to it being duped. Any help would be greatly appreciated.
