Tom Brady's first game at Gillette Stadium in an away uniform is BY FAR the most coveted ticket of the NFL season ... with sales skyrocketing leading up to Sunday's big matchup.
TMZ Sports has learned ... the average ticket price for the Buccaneers vs. Patriots showdown is a whopping $1,222 on StubHub ... with the cheapest seats coming in at $275.
We're told Brady's homecoming is crushing every other game of the NFL season in ticket sales ... outselling the second most popular game by 20%!!
As for who's going to the game -- the majority of fans are from Massachusetts (duh) ... with 8% of spectators coming from California and another 7% coming from Brady's new state of Florida.
The game has been hyped up since the schedule was released back in May ... and many have called it one of the biggest regular season ones in NFL history.
Brady has downplayed the whole thing ... claiming he's not expecting a "homecoming" as it's just another Sunday night game to him.
It may not go as TB12 plans -- after all, the guy is responsible for those 6 Super Bowl banners in the stadium.
But, folks aren't SOL if they want to see it all go down in person -- we're told there are still about 2,200 tix left on StubHub.
