John Stockton autographs have been selling for about 10% less than they were selling for over the last 6-10 months. The John Stockton 03 UD Legends has recently sold for $75 and change (twice) – the lowest I have seen for that card since last September. Other notable Stockton cards that have been selling for less: 05 Fleer Greats of the Game and 06 Chronology MVP Winners. See the John Stockton link to get a better idea of what I mean.
Joe Dumars’ only certified signed NBA card, 97 Skybox Autographics, as seen a slight surge in the last several sales. It normally sells for $10-$15ish, but the last three have all sold for $20+. I know it isn’t much of a hike, but it is just something that caught my eye.
