Only 5 were ever created, this is the first card ever made - numbered 1 of 5. These cards were created and distributed for the 2017 National Sports Cards Convention in 2017 by Leaf who made the card in honor of the fight of the century between Mayweather and McGregor. They printed a small amount of these cards as non auto cards and randomly gave them away at the show. They also made just 5 of these auto versions signed by both Conor McGregor and Floyd Mayweather.
Throughout the show, anyone who paid and ripped an expensive box of Leaf product was entered into a raffle. Each of the 5 days of the show, one person was selected and given one of the 5 grail cards - this card was the first one given away.This is an extremely difficult card to find as they never surface.
