Card collecting is a time-honored tradition for all of the Big Four sports in North America, but it all started with baseball, and the hobby's still alive and well in the sport. Thanks to Shohei Ohtani, it's arguably never thrived more.
New rookie cards are loaded into every Topps release, but the craze for them typically subsides (for example, 2025 prices on Jackson Holliday rookie cards are not what they were in 2024). Former players are still very actively collected — Ken Griffey Jr., Derek Jeter, and Barry Bonds are some of the most commonly chased retired players of the modern era — but demand has plateaued.
