A one-of-a-kind belt will be presented when Floyd Mayweather and John Gotti's grandson meet in the ring next month ... with the World Boxing Council designing a special Juneteenth-themed keepsake for the exhibition.
TBE and John Gotti III are slated to fight on June 11 in Florida ... which falls just over a week before the federal holiday.
Given the historic significance of Juneteenth, we're told the WBC wanted to commemorate the day as part of the weekend's festivities by presenting the unique belts to Floyd, as well as Robert Smith, James McNair, and Jona Rechnitz for their contributions to society.
