It takes one hundred pennies to equal the value of a dollar.The smallest coin in size is the dime.Yet this small coin has twice the value of a nickel, which is larger in size.Of course, you know that a nickel is worth five pennies, it is interesting to note that a dime is worth ten pennies, but is smaller in size than a penny. Dimes are smaller in size than nickels or pennies, yet dimes are greater in value because they are made mainly of silver at greater expense.
