You can find US coins from:
1 (one) cent = 1 cent
5 (five) cents = 5 cents
10 (ten) cents = 10 cents
25 (twenty-five) cents = 25 cents
50 (fifty) cents = 50 cents
1 (one) dollar = 1 dollar
Remember that American coins have a name. For example:
1) the penny is also known as “the penny”.
Ex.: Can you lend me 2 pennies? (Can you lend me 2 cents?)
2) the 5 cent coin is also known as “the nickel”.
Ex.: How much is this candy? (How much does this bullet cost?)
it is a nickel. (It's five cents).
3) the 10 cent coin is also known as “the dime”.
Ex.: Here is your change. the dimension. (Here is your change. Ten cents).
4) and the 25 cent coin is also known as “a quarter”.
Ex.: I need two quarters. Can you lend me until tomorrow? (I need 50 cents/two quarters. Can you lend me until tomorrow?)
Thus, it is important to know the names of the coins, as we can see in the illustrations above, on the 10 and 25 cent coins the value itself does not appear, but only the names: "one dimension" and "quarter dolhome".
50 cent coins, as well as 1 dollar coins, are very rare in the United States, and they can be called “50 (fifty) cents” or “half dollar coin” and the 1 dollar of “the dollar coin”.
As for American banknotes (bills), you can find them in the values of:
1 (one) dollar bill - 1
2 (two) dollar bill - 2 dollars
5 (five) dollar bill - 5
10 (ten) dollar bill - 10 dollars
20 (twenty) dollar bill - 20 dollars
50 (fifty) dollar bill – 50 dollars (also known as “a nifty”)
100 (a hundred) dollar bill – $100 (also known as “a sleeve”)
