I could answer this question in the 1800s, but lets put ourselves in that time and say that you can use 2 cent pieces.
(25) 2 cent pieces
10 x 10c coins
four dimes equal 40 cents ten nickels equal fifty cents ten pennies equal 10 cents Add the 3 groups of coins for one dollar
2 Fifty cent coins. 3 dimes, and 2 pennies.
The answer will depend on which country's dollar: there are many countries that use the dollar as a currency and they have different coinage.
All you need to use is 40 pennies, 8 nickels and 2 dimes.
If you can use up to three types of coins, the answer would be to use a Dollar coin - require only one coin.If you must use exactly three types of coins, the answer would be to use 3 Quarters, 2 Dimes and a Nickel - requires six coins.
1 half dollar,1 quarter,2 dimes,1 nickel
half dollar, quarter, nickel, twenty cent peice ( yes, they do exist)
19 nickels and 5 pennies.
ten dimes Only 1 way if u use exactly 10 coins
10 nickels, 3 dimes and 20 pennies.
