Question concerning 1970 Topps Super Proof

[MCoxon]

Restarting a thread originally on 70 Topps proofs and grading. I see most - but not all -- topps super proofs from 1969-1970 are graded "A". None in 1971.

I just bought a Mays 1969 Topps Super Proof, graded PSA 7. Only 2 total 1969 Topps proofs have a numerical grade (including a 69 Topps super proof Pete Rose PSA 4) as of today. I searched and found 1 proof from 1970 with a number grade (a 1970 square proof blank back, Killebrew PSA 7).

Mine is the only 1969 Topps super proof Mays with a number.

Were these 3 proofs given a numerical grade a grading mistake by PSA? Why this one graded and only 2 others? I understand that many/all proofs were considered sheet cut which is why PSA doesn't typically give a number grade. So, is there something different about this one?

Picture attached.

More than likely the submitter was someone who does a lot of business with them. Could be a mistake also but I highly doubt it.

Here is a blank back square corner, a regular back square corner, and the normal round corner Super.

The blank back is on thinner card stock.

There were also 71 Supers like that. This is a 4 card sheet

1968 Topps Plak checklist all receive a "A" grade except one was graded a PSA 7 ... Not sure what makes that one card worthy of a number grade.

Thanks for that info, interesting. It's the randomness that I don't get. Not sure what makes this one worthy of a number grade either.

Oh well, it's a 1/1 (69 super proof Mays graded) or 1/2 (69 super proof Mays slabbed at all), and I like the card and its photo, so I'll take it.
