To create equal coin collections valued from 1 cent to 1 dollar, you can use just 7 coins: one 1-cent coin (penny), one 5-cent coin (nickel), one 10-cent coin (dime), one 25-cent coin (quarter), and four 1-dollar coins. This combination allows you to represent all values from 1 cent to 1 dollar using various combinations of these coins. Each denomination can be used alone or in combination to form the required values.
One way of doing this is with 19 ten-cent coins and 10 one-cent coins.
25 cent and 10 cent and 1 cent
Just one, a dime.
Three. A 20 cent, 10 cent and 5 cent coin.
Using standard American coins (1, 5, 10, 25 cents), the fewest number of coins to make $0.13 would be four -- one dime and three pennies. This number would be different in countries that use different denomination coins, such as the 2-cent piece.
Two coins
To make 85 cents using the fewest coins possible, you would need one 50-cent coin (a half dollar), one 25-cent coin (a quarter), and one 10-cent coin (a dime). This combination totals 85 cents.
