planchet
A blank with a rim is called a planchet, although it’s acceptable to continue to use ‘blank’ as a general term for a coin before it’s struck. Special proof and uncirculated planchets go through a cleaning process called burnishing to smooth and polish the surface using metal pellets.
What does wrong planchet mean?
Definition: A wrong planchet error is exactly what the name indicates – a coin struck on a planchet intended for another denomination (domestic or foreign). For example, a dime struck on a copper core is off-metal but is not really a wrong planchet. The coin below is both a wrong planchet and an off-metal error.
What is a planchet crack?
When partial breakage instead takes place in the vertical plane or along a steeply oblique plane, the defect is designated a “cracked planchet.” A blank or planchet can crack before, during, or after the strike. While the last two circumstances actually produce a “cracked coin,” that term has never been adopted.
How are planchets used to make a coin?

What happens if you hit a penny with a planchet?
Misdirected planchets – a planchet intended for one “press” gets into the wrong one (i.e. a dime planchet gets struck by a penny die) Many coin dealers sell error coins. The various coin grading companies also classify them. If you happen to find an error coin or planchet in your pocket change, don’t throw it away.
What happens when a planchet is not milled?
The result is a blank planchet, which may or may not be milled. Mint-error collectors look for blank planchets when sorting through a bag of coins, since there is little chance that a blank planchet will be wrapped in a roll or reach circulation undetected. The most basic type of planchet error is when the wrong planchet is fed into a press.
