How do I determine the price of such a card?

Have had this card for about 4 years now, have no clue what to do with it, or even determine anything about it. As for its grade...GMA grades cards based off of alignment, unlike other companies (I don't know if that's true) which is why it has such a low grade to begin with. When I pulled this card, it was sent immediately for grading, so I know it's at least an 8 or more. I just want help determining a value (If it even has one).
