Lamination Flaw -there's a hole right through my coin!

August 22, 2011

1943 Penny with Hole

An impurity in the metal mix used to make the coin planchets can have a spectacular result when this lamination flaw makes it through quality control and the struck coin lands in your pocket. The coin seen above has a hole right through the middle of the planchet! This has been caused by a gas bubble, dirt contamination, foreign material or poorly mixed element in the alloy mix when the sheet of metal was rolled before the planchet was cut and the coin struck.

These sorts of alloy defects can have very differing appearances on a coin as you can see in our previous entries Planchet Flaw Coin Errors and Peel or Lamination Flaw Coin Errors. This example though I think is pretty cool!
