Hawaii Plate Variety?

Is this scratch on Scott #75 a known constant plate variety?

Yes, it looks a lot like a known variety. I can't think of where I got it, but here are screen shots from a great plating book. You might be able to download it somewhere.

parttime - thanks for the info - looks like I have position 32, too bad it has no gum.

Did your stamp also show the dot on the N of Cents? I think that would confirm it.

It certainly looks like almost every stamp has some sort of unique plate position identifying mark. It would be fun to try and collect just this one.

eyeonwall, that's a superb specimen of the error transfer on position LL32-1 (lower left pane, state 1)! The horizontal lines are considered guide lines or scratches, and the diagonal line is an error transfer. I have several of this position, but mine don't show the horizontal line in the A as well as yours due to plate wear.

I have a huge collection of these. I posted several more examples of Hawaii 75 error transfers in the topic below:
