If you come from a major city, such as New York or London, you may find New Mexico overall fairly inexpensive, although Santa Fe will be closer in price to what you're accustomed to. In Taos and Albuquerque, you can still get good accommodations and meals without wincing. Santa Fe, however, may hurt a bit, especially if you hit the hottest spots in town, which cater to sophisticated tastes.
The most common bills are the $1 (a "buck"), $5, $10, and $20 denominations. There are also $2 bills (seldom encountered), $50 bills, and $100 bills (the last two are usually not welcome as payment for small purchases).
Coins come in seven denominations: 1¢ (1 cent, or a penny); 5¢ (5 cents, or a nickel); 10¢ (10 cents, or a dime); 25¢ (25 cents, or a quarter); 50¢ (50 cents, or a half-dollar); the gold-colored Sacagawea coin, worth $1; and the rare silver dollar.
The easiest and best way to get cash away from home is from an ATM (automated teller machine), sometimes referred to as a "cash machine," or "cashpoint." They are available all over New Mexico.
