This is not possible without also using a half-dollar coin. Using only quarters, dimes, nickels and pennies, $1.50 can be made with six or eight coins, but not with seven.
Using six quarters would create a total of $1.50. With only five quarters, the total would be $1.25. This requires coming up with the additional 25 cents using two coins that are not quarters.
