It's not clear exactly what you mean. If you're not from the U.S. and are interested in common nicknames for coins, the six current circulating denominations are as follows:
1¢ - one cent, erroneously called a "penny" by 99.99% of the population
5¢ - called a nickel because it contains that metal
10¢ - a dime, its real name, left over from an obsolete plan for coin values in the early 1800s
25¢ - usually called a quarter, but sometimes "2 bits", left over from its equivalence to an old Spanish coin.
50¢ - half dollar, rarely "4 bits"
$1 - no special name, but slang term is "buck"
