Full Answer

Coins have been made with reeded edges for fraud prevention for nearly as long as coins have been minted using precious metals. When silver coins had smooth edges, clippers carefully shaved away some of the coins' edges and sold the metal for a profit. Adding a reeded edge made it impossible for clippers to remove material from the coin without it being noticed. Nickels and pennies do not have reeded edges because the metals they are made from have never been valuable.
