A three picture set of a die, 1. normal (around MDS); 2. a die crack forms (LMDS); 3. small peice of the die falls out and forms a CUD (a cavity in the die which appears as a raised lump on the coin). Last picture shows the weakness of the strike in the opposing area of the reverse.

And a retained CUD that shows a vertical drop of the broken piece of the die. Coin is a 1964 Australian Penny.
