The point of the units would just to give some sort of weighting system to how you are playing these. The actual amounts are unimportant.
If a 100 dollar per game player comes along, should be play the bigs for 100, the trash for 50, and the BIGG for 200? That's the essential question. If someone wants to use your action, they need to have some idea of your confidence level in the plays.
Otherwise, anyone could randomly throw up 80 plays and then at the end say yep I won because I hit my big ones.
