New Member Saying Hello: Banned From PSA Forums This Morning

[KingKongBundy]

I took a look at the 1970 Topps population report for PSA 10 graded cards. As of today, there are 1414 PSA 10 graded cards out of a total population of 147485 1970 Topps cards graded by PSA.

In the OP's post, I counted 52 1970 Topps cards that received a 10 and I assumed that out of the cards that didn't get assigned a 10 in the submission, 3 of those cards were 1970 Topps.

As such, it would be interesting to calculate the probability that out
of 55 1970 Topps cards submitted, what is the likely-hood that that 52 would be graded PSA 10 assuming 'everything being equal'.

(Back of the envelope calculation ~ 10^-101).

Basically, you have a better chance of winning the powerball lottery 11 times in a row than receiving the grades received in the submission for the 1970 submission alone.

Welcome to the "I've been banned by PSA Club". My question is, what took you so long?

I think there are many who consider it a badge of honor.

That's a very nice gift from PSA. Over $200,000 in cards that otherwise would be worth $40.

He must be a VERY good customer.

I will now think of it as such.

Thank you.

I was a Math major and have always enjoyed statistics and probabilities but I was never trained in the Back of the envelope technique. The calculation looks about right to me. Nothing better then a few numbers to back up claims.

I also checked the list of 1979s and can't find Bo Derek. I believe that was the year she got her 10.
