I know exactly what you are talking about coop. Its not the mintmark I'm talking about, its the raised portion coming off the bottom of the 9. To me it looks like either an old mint mark, a mm that jumped once when the guy was punching it into the die and it landed way off course. Everyone has said they are positive its a die gouge. It exactly fits the corner of a D mint mark for that year range, its a touch thinner because it was punched on the bounce and didnt get the force of a full hit. and if you look at the corresponding line that runs through the 9 you'll notice that line is incuse. If that mark I'm talking about was caused by a gouge then the line that continues extending on from it would be raised through the 9 and not incused, which it is. Think about it, if you accidentally punched a mint mark over a date, the punch wpuld.push the metal away and it would fill any negative spaces on the die in turn causing a small incused ridge on the 9.
