Hi! I’m John Wyllie. Thanks for stopping by.

I have been a dedicated reader and avid collector of vintage Sports Illustrated magazines since 1963.  Since opening my Ebay account in 2005, first known as Jwyllie$ then SportsIllustrated9.8, I have been an integral part of the growing collector interest in high grade or “Graded” Sports Illustrated magazines.  As the popularity for grading SI’s has grown, so have the values and investment opportunities.  What is a CGC 9.6 Cassius Clay SI worth?  It’s really uncharted territory so perhaps it’s time to begin organizing and challenging the market as to values, opportunities, and the subtleties associated with the most critically acclaimed sports periodical ever written.
