10- Coins

Gustavo has a certain amount of coins of 1, 10, 25 and 50 cents, with at least one of each value. It is impossible to combine them in order to get exactly R$ 1,00. What is the largest possible total value for their coins?

Notes

Combine to get R$ 1 is if you have 2 coins of 50 cents you have R$ 1. But if you have 2 coins of 10 cents you have only 20 cents, you can't combine these coins to get RS 1. R$ is Real sign, the Brazil currency. 100 cents is 1 Real.
