Gronkowski and Reggie Jackson Hit the Floor on the National's Final Day
Two hobby heavyweights — Rob Gronkowski and Reggie Jackson — made show-floor appearances on Day 5 of the 2026 National in Rosemont.
What Happened
Rob Gronkowski and Reggie Jackson were among the athletes appearing on the show floor Saturday at the 2026 National Sports Collectors Convention, held at the Donald E. Stephens Convention Center in Rosemont, Illinois. Today is the convention's fifth and final day, running through August 2. The appearances added a marquee close to what has been one of the hobby's biggest annual gatherings.
Why Collectors Should Care
Athlete appearances at the National aren't just a photo op — they move markets. Gronkowski remains one of the most liquid names in football cards, with his certified autos and high-grade rookies drawing consistent demand from NFL collectors. Any in-person signing session or booth appearance refreshes collector attention on his key cards. Reggie Jackson brings a different but equally potent pull: Hall of Fame status, a deep vintage card catalog, and a fanbase that spans baseball purists and crossover collectors chasing certified autos and graded high-number Topps issues. When names like these walk the floor, dealers reprice, collectors dig through their PCs, and submission queues at grading companies tend to tick up in the days that follow. If you're holding Gronk rookies or Reggie Jackson certified autos, this weekend's visibility doesn't hurt.
Questions Collectors Are Asking
Are Gronkowski and Reggie Jackson signing autographs at the National?
Both appeared on the show floor Saturday, but the specific format of their appearances — open signing, ticketed session, or dealer-booth stop — has not been confirmed in available reporting.
Does a National appearance affect card values?
It can. Renewed collector attention around a player's name — especially from a high-visibility event like the National — often prompts fresh sales activity on their key rookies, certified autos, and graded vintage cards in the days following the show.
Is the 2026 National still going on?
Yes — today, August 2, is the fifth and final day of the 2026 National at the Donald E. Stephens Convention Center in Rosemont, Illinois.
