Go to Las Vegas, and find one of the few casinos that still has coin clot 
machines (Circus-Circus? El Cortez?) (where's the excitement in scanning a 
credit card, and winning a piece of paper to take to the cashier's cage?), 
and buy a dollar coin.  It is the casino's imitation of a silver dollar. 
Put it into a slot machine, and you will never see it again.  Unless the 
machine malfunctions and spits out one or more into a bowl that is 
optimized for making loud noise.
