As determined by factory cost vs current selling price according to this link posted by DealerNetB2B on Twitter earlier today. What do you think is on the list? 2010 Bowman Draft Picks and Prospects and the chase for Strasburg? 2011 Bowman Chrome Baseball and the chase for Harper? Football products from 2004 with Eli Manning RC's?
Nope, nope, and nope. In fact 20 of the Top 25 products are basketball. Only a single product from the other major 3 sports (football, hockey, baseball), golf, and Yu-Gi-Ho made the list.
Now you could analyze each of these products and come up with multiple reasons why they are selling at the prices they are but at the core is the international fascination with the game and the deep pocketed speculators that are attracted to the hobby from a purely investment standpoint.
High-end basketball singles repeatedly and continually return a greater percentage from sales on the secondary market than any other sport. It's also one of the reasons basketball was the first genre to have a $500 per pack product.
When I saw this list, it was no surprise that 2003-04 Exquisite was at the top of the list. However, I must admit I was surprised to see the sport so thoroughly dominate such a list in its entirety. I suppose I shouldn't have been.
Baseball may rule the vintage market but when it comes to modern wax, no sport can touch basketball.
