Dollars

Every time going back home on business trip my pocket is fulled with coins. I used to put them in the basket for donation, UNICEF, at an airplane or airport. It was always hard to use and count the coins as an alien.

US paper currency has had many nick names. The notes themselves are generally referred to as bills and any combination of US notes and coins as bucks. - Federal Reserve Note from Wikipedia

(그러니까 five-dollar bill 또는 fifty bucks 이렇게 얘기하는 거다)

• Bill or Paper money

1. Banknotes
   There are 7 types of bills that are currently used, $1, $2, $5, $10, $20 $50, and $100. I hardly see to use bills larger than $20.
   
   (실생활에서는 $20 까지만 많이 쓰는 모양이다. 처음 미국 출장 갔을 때 Market에서 약간의 물건을 사고 $50를 내밀었더니 점원이 당황하던 기억이 난다.)
   
   
2. Large denominations
   Today, there is no bill larger than $100. At one time, however, 5 larger denominations, $500, $1,000, $5,000, $10,000, $100,000 were issued. One thousand dollars can be referenced as "Large", "K", "Grand or "Stack".
   

• Coinage

1. Today circulating coins exist in denominations: $0.01, $0.05, $0.10, $0.25, $0.50, and $1.00.
   
   (1¢(Cent)는 Penny로 100개 있어야 $1가 된다. 우리식으로하면 10원. 5¢는 Nickel 그러니까 50원. 10¢는 1Dime이며 1¢보다 작다. 100원에 해당하니 만만히 볼 넘이 아니다. 다음 $1/4에 해당하는 Quarter가 있다. 우리식으로 하면 250원이니 애매하다. 이외에 50¢(50-cent, Half dollar or piece)와 $1(Golden dollar)가 있는데 잘 통용되지는 않는다고 한다. )
