What is the value of a 2004 silver nickel?

NICKEL, not "nickle"

And not silver, either. The only 5-cent pieces to contain any silver were "war nickels" made during WW 2 because nickel was a strategic metal.

Those corrections aside, your coin is only worth 5¢ if it came from pocket change. Billions were minted. The design celebrates the Lewis and Clark expedition. They're not seen much in circulation because people saved them as curiOSities.
