How much are buffalo head nickels without any dates on them worth?

They usually sell for about 10 to 15 cents. Crafty people use them to decorate belts and make domed buttons.

Note that these coins are called Buffalo Nickels or Indian Head Nickels, but not "Buffalo Head" nickels. After all, they show the whole buffalo and not just its head!

=========================

The mint mark will be located on the back side under the Words FIVE CENTS. Nickels minted in Philadelphia do not have a letter, though. Also, nickels minted from 1913 to 1925 had a design flaw that allowed their dates to wear off quickly. Unfortunately these "cull" nickels aren't worth much more than face value.
