I don't think there are different versions of the Henderson rookie. I'm sure with any 1980 card you are going to have a fair number OC and a good number that are centered. What I focused on in the video is what happens when a collector submits a card to PSA that they think should be either a 9 or 10 (and PSA agrees). What happens then? The answer is that 81x more often PSA is giving that card a 9. That's what I find so strange and what seems counter to the way other vintage cards are graded. From what I've seen on a number of cards, when a card has a low number of 10's, we see a low number of 9's too.
