The answer is 1 quarter, 5 dimes, and 2 pennies.
Since the ones digit of the number of cents (77) is 7, then there are two ways of achieving the answer.
1) 7 pennies. This possibility is ruled out since there are only 8 coins.
2) An odd number of either quarters or nickels and 2 pennies. Since there are no nickels, 3 quarters would use only 5 coins total, and any more than 3 is too much money, we have 1 quarter and 2 pennies.
That means that the number of quarters and pennies is worth $0.27. The remaining 5 coins are then all dimes, which make up the remaining $0.50.

How about:
3 quarters, two pennies. That's five coins totalling $0.77.
Then you make the other three pennies silver dollars and go buy yourself a beer... if you're old enough.
