I know in the 1990's it was announced all the time, especially during the Teen and College championships, that the players received exactly what the earned if they were above the minimum.
However, on the Tournament of Champions, the day someone goes over the minimum mark (unless it's still at $100,000, then it's possible) will be the day we find an ultimate Jeopardy champion. People knew it was an accomplishment, especially with the material difficulty and who was playing, to even get $25,000 in a tournament of champions before the stakes were doubled.
