Seller at 69 Keys

Although 65 Keys could be argued as a quicksell, it's probably not too low considering the seller at 69. It's WAY better than it's current price anyways.

Only useable sale I could find, 65 Keys should be fine.

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