(Sorry, but the poll is silly. No offense. If it's NOT a pen or marker type of a mark on the back, then most of the choices are eliminated.)

Yeah, is that just a regular, non-TPG type of holder it's in, or is it already in an SGC slab?

The blue on back definitely looks to be a print defect (PD), so if it doesn't get that qualifier, then it will cause the grade to drop, but it's anyone's guess how many numbers lower that would be.

Is the card severely bowed? Or is it miscut on the lower left there? This card is notorious for coming back as 'Authentic - Miscut' from PSA, because of the strange way it was cut at the factory. I have one, in fact. If it's bowing, then maybe you need to take an iron to it to flatten it out a bit before submitting.

Good luck!!
