This might seem insane because when Ned Stark became the right hand he learnt that they would host a tournament which offered 40,000 Gold Dragons to the winner of the joust, 20,000 to the runner up, and 20,000 to the best archer. If we did the math that would equal a total of around a quarter billion US dollars of tournament rewards. That’s just what the Game of Thrones Wiki states so I will work around that.
