Lesson 9: Money

# U.S. coins review

Review the value of U.S. coins, and try some practice problems.

## U.S. Coins

The most commonly used coins in U.S. money are $\text{quarters}$, $\text{dimes}$, $\text{nickels}$, and $\text{pennies}$.

### Quarters

$\text{Quarters}$ are worth $25$ cents. Below is an image of the front and back of a quarter.

### Dimes

$\text{Dimes}$ are worth $10$ cents. Below is an image of the front and back of a dime.

### Nickels

$\text{Nickels}$ are worth $5$ cents. Below is an image of the front and back of a nickel.

### Pennies

$\text{Pennies}$ are worth $1$ cent. Below is an image of the front and back of a penny.

## Counting coins

Let's look at an example:
What is the total value of the coins below?
One quarter is $25$ cents.
$25$ cents
A dime is $10$ cents, and there are $2$ dimes. Skip count by $10$'s two times from $25$ cents:
$25,35,45$ cents
A nickel is $5$ cents, and there are $2$ nickels. Skip count by $5$'s two times from $45$ cents:
$45,50,55$ cents
A penny is $1$ cent, and there are $4$ pennies. Count by $1$'s four times from $55$ cents
$55,56,57,58,59$
The total value of the coins is $59$ cents.

## Want to join the conversation?

• Why did they decide to call a cent a penny?
• The British pound was not divided into 100 cents like our dollar, but its smallest part was called a penny, and that's why we call our cent a “penny” today. But for more than one, the British called them “pence” while ours are called “pennies.”
According to usmint.gov
• why is it called a dime?
• The original dimes, minted in the late 1700's, were called dismes (still pronounced like dime, or deem). Disme is an archaic term in French, or another romance language (my memory isn't what it once was) that means 10. Since a dime is 10 cents, the name makes sense, and the dime isn't named after anything but its value. Hope this helped!
• are they actually going to make a 20 dollar bill?
• The 20 dollar bill has been around basically since the existence of the US currency system. Every bill minted since 1861 can still be redeemed. The 20 dollar bill has had Andrew Jackson's face since 1928, before which it had Grover Cleveland's face on it. Some people have asked for a redesign of the bill in recent times, with a woman's portrait, but none of these bills have actually been circulated.
• If you use U.S. money to pay for things in the U.S.

what would happen if you used different money from different places, or if you use 2 dollar bills (if you still have one)?
• Most US locations wouldn't accept other countries' currencies, so you would most likely have to get it exchanged and turned into US dollars if you were staying for any length of time. 2 dollar bills are still legal tender and are still in production, so while it would probably be unusual, it wouldn't raise any red flags if you tried to pay with a \$2 bill. Hope this helps!
• what happen to the 1000 dollar bill
• They stopped printing the bill in 1946, but the bill continued to circulate till 1969 when the federal reserve recall them.
• Why is a nickel bigger than a dime?
