One dollar can be made by adding the values of the following 21 U.S. coins:
10 pennies (10 ¢)
7 nickels (35 ¢)
3 dimes (30 ¢)
1 quarter (25 ¢)
There are also many other possible configurations including:
10 pennies (10 ¢)
4 nickels (20 ¢)
7 dimes (70 ¢)
and
5 pennies (5 ¢)
13 nickels (65 ¢)
3 dimes (30 ¢)
Well, isn't that a happy little question! If we take a moment to think about it, we can see that 4 quarters make a dollar, and adding 21 more pennies will also make a dollar. So, 4 quarters and 21 pennies together make 25 coins that add up to a dollar. Just remember, there are many ways to make a dollar with coins, so feel free to explore and create your own combinations!

You cant unless you have 100 pennies.
I'd say you can't. If all the coins are the smallest possible without pennies, they must all be nickels, and 21 of them make $1.05 . So in order for 21 coins to be not more than $1.00, there must be some pennies.
(1) $0.50 (2) $0.10 (3) $0.05 (15) $0.01
3 dimes 13 nickles 5 pennies

Not in the US.
5*20 cents (Australian) make a dollar. In US and Canadian coins, a 50 cent piece, a quarter, two dimes, and a nickel also make a dollar.
