In baseball, few pieces of memorabilia are more distinct than the bat knob. While hundreds if not thousands of pieces can be taken from the other parts of a bat, there's just one knob. It's similar to a Logoman or special patch in that regard. Size comes into play on these as well because they're bulk, adding a depth and some heft to the card. Add a signature into the mix and you've got some of the most desirable baseball cards out there.
As far as brands go, none are more synonymous with bat knobs than Topps Tier One. They have been connected to the line for years, offering one of the product's chase hits and giving collectors deep checklists in the process.
Shohei Ohtani is one of 25 players with autographed bat knobs in 2020 Topps Tier One Baseball. This is his first signed knob card and one of just three that he's had in Tier One. The black knob is accompanied by a bold 10-grade signature.
The certification number on this card has been checked against the third-party grader's online database and is active as of 10/06/2025.
