Do they ever explain the methodology by which the comparison books are chosen? Before results are known, or after? I’m not disputing the general premise, but I’m wondering if there is some mechanism in place that prevents specific cherry-picking after results are known. Because that would be like being both judge and contestant in a beauty contest.

I don't see anywhere what the methodology is. I suspect the activity of the top contenders is ringing some bell of performance. Key Comics would probably consider their analytics to be proprietary, not likely to share.

As it stands, it's only 1 company's opinion.

There are data integrity and consistency issues throughout keycollector (and similar sites).

An example in the Invincible 1 commentary:
The highest CBCS 9.8 sale was $2,899 vs CGC 9.4 of $3,800, a difference of $901 (31%)

I'm wondering if that involved a typo, cuz they seem to go out of their way otherwise to find direct comparisons.

Typo or not, it’s an error. They (and gocollect) have inconsistent data … consistently.

That's on par with just about every company in recent times. No oversight, no proofing, no accuracy to begin with, and no accountability. Everyone just chalks it up as 'My bad".

It is a typo, you can see above they show a 9.8 sale for $3,800, not a 9.4. Looking closer I can see that these books are 1-5 on the “CGC Monthly Report”, in reverse order. I just can’t find any info on what qualifies a book for their ranking onthe CGC Monthly Report. The cynical side of me wonders if it has something to do with how CGC sales prices compared to CBCS sales…after the results were known.
