1 quarter = 25 cents
1 dime = 10 cents
1 nickel = 5 cents
1 penny = 1 cent
4 dimes, 4 nickels, or 4 pennies would not get you to 60 and 4 quarters would be too much, so you need to have a combination of different coins.
Since it is a whole ten number, pennies are probably not one of the coins used, and if nickels are used there would need to be two. The same goes for quarters, there would need to be two, unless a nickel is used.
I think with this information, you should be able to come to a conclusion of what coins were used.
