Mario's currency SOLVED (Theory)

So one time, i was playing Super Mario Galaxy 2. I was messing around the hub world, and i entered the dice room. In it, you can pay coins or starbits to roll a dice, which can give you 1-ups.

It costs 30 starbits to have 1 roll, and 100 coins to have 5 rolls. Doing some simple math tells us that 5 rolls are equal to 150 starbits. Doing more math says that 1 coin is worth 1.5 starbits. Then i had a question: can all Mario currency's be solved like this? Some can (Some coins don't have an actual value). In Mario Odyssey, picking up a purple coin you already have gives you 2 yellow coins, so 1 yellow coin is worth 0.5 purple coins. After that, we can use similar calculations to figure out other types of coins. Here's a quick list:

1 coin is worth:

1.5 starbits

0.5 purple coins

0.5 red coins

0.2 blue coins

2 frog coins

From here, all we need is the value of a yellow gold coin. But the Marioverse doesn't have an answer. A suit made completely out of gold is worth 3000 coins, but a suit made completely out of metal is also worth 3000 coins.
The black outfit is worth 200 coins,
but the sunshine outfit is worth 4500 coins.
The Mario universe can't answer this question... but our universe can! In some of the Mario games, collecting 100 coins gives you an extra life. In real life, Google says the life of a human is worth at least 6 million dollars. 6 million divided by 100 is 60000. 1 gold coin is worth 60000$, and they are just lying around in huge piles!
There are dozens and dozens of coins in every single level! This proves the Mario world is QUITE messed up.
