GPA attempts to record every public sale for CGC-graded books (of course, he doesn't have data on CLink sales, sales by many dealers, or private sales), while Overstreet is a price guide that attempts to reflect market conditions but doesn't adjust prices to every sale. Overstreet clearly (intentionally) lags behind books that suddenly take off (and sometimes also books that have entered a prolonged decline). Room for both approaches, I guess. I DEFINITELY appreciate Overstreet when I’m picking my tier category for CGC submissions. Sqeggs and shortboxed 2 Link to comment Share on other sites More sharing options...
