US Monetary System

The US Monetary System is a decimal system, with one dollar equal to one hundred cents. One dollar is written as $1 or $1.00. One cent is written as 1¢. One dollar and twenty-five cents would be written as $1.25. Dollar amounts are written with a comma every three digits, so one thousand dollars would be written as $1,000.00. Paper currency is used for amounts of $1 or more, and coins are used for amounts under $1. The most common coins and their dollar equivalencies are as follows:

Coin	Value (Cents)	Value (Dollars)
Penny	1 cent	0.01 dollars
Nickel	5 cents	0.05 dollars
Dime	5 cents	0.10 dollars
Quarter	25 cents	0.25 dollars
Half Dollar	50 cents	0.50 dollars
Dollar	100 cents	1.00 dollars

Paper currency is most often circulated in the following denominations: $1, $5, $10, $20, $50, and $100. Occasionally you will encounter a $2 bill. The denomination of all currency is clearly marked on the bottom of both sides of the bill, and on all four corners. Some stores will not accept bills larger than a $20.
