As for as I know, this item did not sell in the Auction. I personally looked at the note before the auction, and do still question the authenticity of the colour variant.
The Auction itself cannot confirm that this is a true error “Off colour on front probably due to low ink. VF” was their statement, and this places the note in the fence with collectors, some believing it is a real error and others believing it is a fabricated error.
At $325 + the juice, I did not see value in this note as an investment note, with the “yes it is” “no it’s not” stigma.
If one must put a value on such a note, and especially due to its condition, I would consider this to be a possible minor error with a premium of a few dollars over face up to a max of $30. Or it is worth as much as the buyer will pay.
