*The Gatsby is duped, but there's no recent sales for it besides this one so I'm going with the clean one's price(can't be much of a difference anyways)

One sale at 10, one at 11 and another one at 12. 10-12 seems to fit fine.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
