Well logically, 3 winners, 22-25 rounds (some years they did finals too I think). So 66-75 sets.
But some years also had 2 games, Top Team and 4 Star so that's 132-150 sets.
Then some people say some people don't redeem the cards and Teamcoach know it so they don't produce that much.
There's also the belief they produce more just in case.
They also produced extras for the prize frames which were dependant on the winner's favourite team. I think these were 6th to 10th. So these would need to be over produced incase the 5 winners from 22-25 weeks all supported the one team.
So in summary...
NO ONE EVER KNOWS EXCEPT FOR THE PEOPLE AT TEAMCOACH
