I just came across this story about a guy who put his 52 topps/51 bowman autgraphed mantle rookies up for auction.

The author makes it sound like a big deal that mantle signed "best wishes" and it's also kinda funny how he accentuates that mantle signed for "free!"
Does the "best wishes" add value?????
