Pro crossover to PSA

miami3

A couple of years back when I was young and naive I purchased a 62 willie mays #300 in a PRO-8 grade.

The card looked too good in the ebay scan to pass up and the price was right.

After I received the card, I thought that it looked like a psa 8 but might have been undersized in the height.

I then proceeded to show the card to about 8-10 "big dealers" and got a 50-50 response if it was in fact trimmed or not. A couple of guys thought it was from a presentation set because the color and focus was so clear.

So, I decided to take a chance and crack it out of the PRO holder and sent it in to psa for grading.

The good news is that psa graded it within 2 weeks and deemed it to be not trimmed.

The bad new is that it came back a psa 7!

You should consider yourself lucky. Read this: PRO Gradding experiment

Alan,

I've read a few articles by Bruce before... But, that one has to be the coolest and cruelest one to date! Talk about confirming peoples perceptions!!!

I may have to rethink my plans for my Pro-10 71 Topps Set!!!

Bruce,
Awesome job on gathering this information for us to look at. I have wanted to do this on two different types of examples.
1. Sending in 20 cards to PSA with a mix of 6/7/8 quality. Then breaking all twenty out and resubmitting all the PSA 8's on one invoice, all the PSA 7's on one and the PSA 6's on the other. I believe we would see a large difference of opinion.
2. Crossover for BGS to PSA: SGC to PSA:

Great job.

Whatever you do, do not crack it out of the PSA 7 holder. You got really lucky and don't take the chance of getting it "evidence of trimming" while shooting for an 8.

brucemo, that is a great read. Thanks for sharing your experiment.

A PRO 8 coming back a PSA 7?! What is happening? You should be elated! That is probably the best PRO to PSA crossover ever!

In general, the equation for converting a PRO grade to a PSA grade is: PSA = (0.5 x PRO) - 1 .

In general, the equation for converting a PRO grade to a PSA grade is: PSA = (0.5 x PRO) - 1

IMHO, a better formula would be PSA = "Evid. Trim"

I hope "PSA" was meant to be "PRO" in your equation. I will agree with that statement and revise my equation:

If PRO Grade > 7, PSA Grade = "EVID TRIM". If PRO Grade < 7, PSA Grade = (0.5 x PRO) - 1.

Bruce,

I guess you are right, a psa 7 is a lot better than a evidence trimmed card any day!

I actually have two other 62 Mays #300 cards in psa 8 that do not look nearly as good as the 7.

Great job on the PRO experiment. I thick you should call 60 minutes and do a story on grading companies to let the whole world know whats going on.
