How long before the Census has an effect...

[COI]

Almost all prices were way high in 2001. Not much stuff that's as high or higher than books were in 01.

 

That's definetly true for the post-66' stuff in ultra high grade(9.6+). But there have been a few early silvers, particularly in the 9.0-9.2 levels, that would be a bargain today. I attribute this to the fact that the those issues have seen very little increase in census activity(stuff like early FF's) even at the 9.0-9.2 level. And I bet, at that time, a lot of buyers thought it would be more likely that we would be seeing more 9.0-9.2's of those early books, and less likely we would be seeing more 9.6+ of these late silvers. But the opposite has happened.
