What is the value of a silver 1925 buffalo head nickel?

To clear things up:

> It's not silver; all buffalo nickels were struck in the same alloy of 25% nickel and 75% copper used for modern nickels.

> It's also not a "buffalo head nickel"; it's either "Indian head" or "buffalo", but not "buffalo head". Buffalo nickels show the whole animal!
