Perhaps another look should be given to that coin since most five cent coins bear the portrait of Thomas Jefferson.
It's just a nickel, spend it.
The value of a 2006 Washington liberty nickel is five cents. It's a common US nickel, but:It's not Washington; he's on the quarter. All US nickels since 1938 have depicted Thomas JeffersonIt's also not a Liberty nickel. Liberty nickels were struck from 1883 to 1912.
In average condition, both coins are only worth their face value.
No 2005 Bison Reverse nickels were struck in silver.
Face value.
Yes. 5 cents. The obverse of the nickel was redesigned in 2005. They all look like that.
If you got it in change, 5 cents.
Please look at your "nickel" more closely. It says Quarter Dollar right under Washington's portrait. It's one of the State Quarters minted from 1999 to 2009. If you found it in change it's only worth 25¢.
The reason they're called Jefferson nickels and Washington quarters is that Jefferson is on the nickel and Washington is on the quarter. In any case 1946 is not a rare year for nickels, see the Related Question.
If the intended question is about its value, it's worth 5 cents.
Why was, and who recalled the 2005 nickel?
Try that again. Washington is on the quarter, and Jefferson is on the nickel. To give a specific value, ask about a specific date.
