  I've seen them mentioned for years, they often called them "yellow jackets". I'm not sure I believe all the stories of how they were made by the mint using/getting planchets meant for tokens or something by mistake. Seems odd it would happen over different years. I'm not sure what the real story is, maybe nobody knows
  
  Here's a link to Koinpro and he does list some of them:

  The Mint doesn’t make because the planchet making process is farmed out to a subcontractor. Used to be the Ball Corp in TN, not sure if they are the current suppliers.
  If the copper plating solution at the factory becomes saturated with zinc from the raw planchets it becomes brass because copper + zinc = brass.
  You can make your own by holding a penny over your zippo and the heat diffuses the zinc core into the copper layer making it yellow.
  Coins struck on an off-metal planchet is an entirely different thing, a true error, as the Mint struck similar size coins for other countries on different composition planchets, of which some became mixed with planchets intended for US coinage.
  

  Change that we can believe in is that change which is 90% silver.
