Ever since the dawn of online auction sites, collectors have been buying and selling baseball cards on eBay.

In fact, baseball cards and similar other collectibles, like comic books, postcards, and vintage toys helped form the backbone of the budding a behemoth through its early years. Yes, long before many folks outside the hobby had even heard of eBay’s, collectors were greasing the skids for the platform’s future growth, pumping money into the system as we bought and sold cards with fellow collectors (and dealers) we might never have encountered otherwise.

And, with the hobby boom of the 2020s, the ecommerce giant has become even more vital to moving cards from those who have them to those who want them.

On a typical day, thousands of new eBay listings are posted, offering up just about every kind of card you can imagine, and thousands of other lots change hands. But some cards — some listings — make a lot more noise than others, garnering loads of bids and collecting many other “watchers” as their sale progresses.

Keeping an eye on the trends among these “most watched” baseball cards on eBay can be a great way to keep up with the rapidly changing winds and sentiments in this hobby.

To help with that, we present below the hottest baseball cards on eBay right now as determined by the number of watchers for each lot.
