Yes, it's Turner # OB2-RB1 which was on appro 6% of the 1858 large cents. The OB2 Obverse (6% of the total '58's) was only paired with Reverse RB1. It's on p 272 of the 2011 Charlton variety guide at about a 50% premium over a normal 1858 and is a die chip and crack, not a scratch. . You made a very good buy to find this.
