U.S. coins and currency
The main currency in the US is dollar, equal to 100 cents. The coins are usually called: one cent = penny; five cents = nickel; ten cents = dime; 25 cents = quarter. Gold dollar coins today are infrequently used and some stores and restaurants do not accept them. Try not to count your money in open/public areas and try to keep $50 and $100 bills completely out of sight. Banks in New York are open weekdays from 9 a. m. to 4 p. m., and some branches are usually open on Saturday and Sunday.

Sales tax is usually not included in the price tags on merchandise but is added at the cash register.
