Info on Pop Report Issues, Here in One Place

[GregMitch34]

Much has been said about this scattered about so I thought I would ask key questions here to get best expert facts in one place. This seems to be an increasingly key issue as more t206 people seem to base collecting of certain issues on the pop report numbers. So here goes. Note: This does not take up separate issue of good cards that have never been graded.

1) When exactly did PSA and SGC starting breaking out the t206 backs on pop reports? I've seen references to everything from four years to 10 years. Surely this can be nailed down.

2) Did they always keep track internally but not break out for public, and then added to pop numbers when they did go public? For example, with very rare backs? Or did they literally never track that at all. Also: If they now see a card with back they haven't listed up for sale somewhere do they ever go in and add to pop report?

3) PSA lists number of cards with no back info so you can get some idea of what is not in pop reports. I don't see that with SGC. Does that exist?

4) Despite warnings that "highest graded" might very well not be "highest graded" how often does it seem that unlisted higher graded cards turn up? Seems like it does not deter many people.

Feel free to raise any other facts. Thanks.
