No. They don't do that with any COAs.
Well, in the case of the Gaines' books, they were ranked 1 through 12 and it would be interesting to see how the CGC grades compared. I owned the #2 Piracy set and then upgraded to #1 when it became available...
Sold them many years back.
Some of the #1 Piracy copies were not the highest after being CGC graded. clink had the set (ungraded) and when I inquired about the price it was way too much for what I knew the variance in grades was likely to be.
I know of many cases where the certificates were intentionally switched by both dealers & collectors in order to sell a "lower number" Gaines copy. At this point, it really does not matter if you got copy #1, 5, 8, or whatever. As long as it is a Gaines copy, that's what is important.
Timely, you and Adam Strange both, are always appreciated for your insight and knowledge. This all makes a lot of sense. (thumbs u
