Do you agree with this list much? Putting #2 at the top and #6 at third made me immediately raise an eyebrow. However, I do recognize that I've got the benefit of the Internet and its population-estimating tools such as the CGC Census, online auction sites, and GPA available to me that Gary Carter certainly didn't have back in 1995.
I think #6 and #8 are about the only misses near the top of their list. I think #2 is a relatively tough book and the census backs that up.
Also, the list was put together before a lot of the Silver Age pedigrees surfaced. No Northlands, no Pacific Coasts, no Curators, etc. But even so, I think they mostly got it right.
