Interesting. I would imagine with so many cards in production there would be some errors. I say these error cards fetch greater value because of there rarity. Especially the off center card. Thanks for sharing
In the card grading industry uneven borders receive a lower grade, therefore always are lesser valued. It's easy to misalign, it's harder to perfectly produce an individual card repeatedly at mass scale.
As for ink coloring printing differences... Those end up to the preference of the secondary market. Sometimes it matters to the value sometimes it doesn't.
