Personally, my thought is that card was slipped in a 9 holder.

Always a possibility I guess?

Based on the seller and lack of frosting, I don't think the card was switched. Although if I were PSA, I would want to buy the card back and regrade it properly. Since the shade of blue is close to the name box right below it, that's why I was figuring PD rather than MK but it could be either.

There is also a faint mark/spot, either PD or MK, beside "1966" on the back outside border.

You're likely right about it being a PD based on the color of printing ink and also likely right about it not being a switched card based on the lack of frosting, but it sure makes one wonder what PSA were thinking when they graded that card?
