Millions? I mean there are plenty of certified insert autos but they sell for a lot of money. I rarely ever see playing days in person signed cards. I bought a signed 89 Hoops for $500 years ago and the last time it sold it went for multiple thousands. The majority of Jordan items I see in the hobby are UDA baseballs and basketballs along with select prints. If you want anything else I find slim pickings.
