The Wrong Planchet Stock Errors.
When a coin is struck on the wrong planchet, this means coin was struck on the blank (planchet) that was made for another denomination. Some examples would be a 10 Cents planchet struck with 20 Cents dies. A 5 Cents planchet struck with I Cent or 10 Cents dies. Coins struck on the wrong planchet are rare and demand a higher premium. A much rarer error is a Malaysia denomination struck on a foreign planchet.
