I think you mean 'find a penny pick it up' some people believe if the penny is face up you need to give it away or you will loose money. If I were you I wouldn't be throwing 100$ bills on the ground hoping to find 200$, I would take that 100$ and open a savings account so it could grow however slowly. If I'm in the mood for giving away money I'll donate to a food bank or World Wildlife instead.
There are attraction spells for money that involve actual money. I have a wealth jar spell that you need to throw 9 pennies, 9 nickels, 9 dimes, 9 quarters, and 9 loonies [or pounds or dollar bills] into a jar with some other items [all in nines] and keep it in the north corner of your house to attract money. Even then you still have the money if needed desperately.
