They should have access to past sales data kept by PSA and Goldin. If the 2000-2010 ( which would include data from the Great Recession) is suspect then I would not think the current collected data is any more reliable. |
Perhaps sparse is a better word than suspect. I'm not convinced that a lot of the sales data was picked up during the window from 2000-2010.
Go ahead and do a search using the PSA data for any given card at any given grade, particularly cards with a lot of historical volume. My experience is that the data thins out dramatically starting at around 2010, give or take. Often the data drops dramatically, by a factor of 5x or 10x as you go back in time prior to 2010. So either there were fewer sales back then, or just as likely, the data tracking systems weren't capturing as many sales.
Of course, it could also be an issue where there just weren't as many PSA-graded cards period during that era, in which case there wouldn't be as many sales. But as such, the data is a lot less robust, and therefore much more difficult when it comes to parsing the data to reach reliable conclusions.
