What's going on at PSA in their T206 pop report?

Total without Any Brand Info
220.8k – 180.0k = 40.8k

That means over the past couple weeks that ~600 cards were graded (and I can literally account for around 5% of them myself, not joking).

And if the dwellers of Olympus can be bothered to respond to anyone, I'm curious if this is what really happened. The numbers make sense.

In January 2012 I printed out the pop reports for all of the backs, there were 63,222 unknown backs and the total cards graded was 136,903.

There was 34 Magie errors in the pop reprts then.

The plot thickens.

(I do find this exercise of consequence because I am interested in estimating actual populations of individual cards.)

I was wondering if the difference you had was the second era of T206 labels. The first would be when no brand was identified (with my botec of 40.2k), the second would be brand without series and factory, and the third is the current with full information.

If one adds up the second era and subtracts it out, I ended up with 68.3k. I thought it'd be close to your number from an early eyeballing, but you have 63.2k. (If one takes out Sovereign and either American Beauty or Cycle, it gets scary close, but gotta count 'em all.)

So that falls apart.

I'll just wait for the answer, like everyone.

And if anyone does ask them, could you also ask why only Southern Leaguers are broken out under the Old Mill counts?
