What is a U.S nickel worth?

Answer 1

5 cents. That's 1/20 of a dollar.

The above answer applies only to the coin's face value, i.e. its denomination. A nickel can be worth much more if it's a rare date or mint mark, but you have to specify both of those details to have an idea of its value.

In any case most nickels that you find in circulation and that are dated after 1946 are only worth face value, 5 cents, unless they're in like-new condition. And pretty much any nickel minted since the early 1960s will be worth only 5 cents unless it's uncirculated.

Answer 2

NICKEL, not "nickle"

If it's newer than say 1946 and you found it in change it's only worth 5 to 10 cents unless it's a 1950-D nickel.

If it's older than that you'll need to post a new question with more details. What's the coin's date? Does it have a mint mark (a small D or S)?
