| Less than 40 years ago in the United
States, it was common to change a one-dollar bill for a dollar’s worth of
silver. That is because the coins were actually made of silver. But those days
are gone. There is no silver in today’s coins. When the price of the precious
metal rises above its face value as money, the metal will become more valuable
in other uses. Silver coins are no longer in circulation because the silver in
coins is worth much more than their face value. A silver firm could find that it
is cheaper to obtain silver by melting down coins than by buying it on the
commodity markets. Coins today are made of an alloy of cheaper metals.
