Normally, when a high-profile player is in the middle of a playoff run like the Spurs' Dylan Harper, we see a spike in demand and prices for their cards. One need only look at Shai Gilgeous-Alexander for proof of this, as his prominent role in the Thunder's postseason push, along with winning another MVP award, has his card market white-hot at the moment. However, Harper seems to be a different case altogether.
Harper has been perfectly fine during the playoffs so far. Across 13 games, he's averaged 14.4 points, 5.3 rebounds, and 2.5 assists per game. They're certainly not the eye-grabbing numbers that we have grown accustomed to seeing out of Victor Wembanyama, but there have been some good games from Harper mixed in ... and Harper IS still one of the top rookies in NBA card products right now.
After it was revealed that Harper suffered a hamstring injury in Game 2 on Wednesday, it seems logical to expect a steady increase in the prices for Harper's premier rookie cards over the last few weeks, followed by a sudden dip.
Dylan Harper's Spurs card market seems to be surprisingly resilient to changes
Unlike Cooper Flagg and Kon Knueppel, both of whom actively being chased by collectors all season long, it seems Harper has encouraged more of a long-term hold approach from hobbyists. The prices are generally strong for a rookie, but we haven't really seen much of a spike in demand as much as a slow and steady climb without interruptions so far.
Let's take Harper's base rookie auto from Topps Chrome as an example, as it is a flagship card and one that is pretty representative of the 20-year-old's standing in the marketplace. In January of 2026, you could get a raw version of the card for around $250. In April 2026, the price was pretty much the same, with a very modest dip and rise in between. The last month or so have seen Harper's Chrome rookie auto climb to a little over $300, but it has been a very gradual rise and not the spikes we have seen from other playoff performers.
That seems to speak to how collectors feel about Harper at the moment. They like him and, as a former No. 2 overall pick, there is value in dabbling in his market, but he isn't causing wildspread hysteria with his products. There seems to be little desire for short-term flips for his cards, which bodes well for his value holding up despite his injury. Of course, all bets are off if his hamstring injury is serious and the Spurs bow out as a result, though.
