A miscut is either when part of your card is cut off OR you have part of an adjoining card showing up. So this card, if it was an EX 5 otherwise, would get a 5(MC) grade and the stain would be ignored. PSA doesn't award or even mention a second qualifier on a card. For a registry set, cards with grades above 2 lose 2 grades for what they equate to, so this would be a 3 if you counted it towards a registry set. If the other card wasn't visible on the back, it would be a 5(OC). Same basic result. Most qualifier cards will be priced around the same as a card 2 grades lower, but since yours has multiple problems and is severely off-center, it might be valued four grades lower.
