Strange; I rarely think of the cash award with the Nobel prize.
Beyond the hunk of gold, they could also have the king of Sweden hand you the hunk of gold. I think that's a good touch.
If one of the wealthiest people in the world won a Nobel prize, nobody would say "billionaire and $1M prize winner, et cetera".
The "Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel" is almost invariably called the "Nobel Prize in Economics", even though it's a separate deal that didn't exist until 1969.
