Extremely difficult to obtain both halves of a completely split planchette coin! Usually with clamshell error coins they are found still intact and only partially splitting. Or if completely split in half most commonly only 1 half of the coin is found.

A split planchette coin error occurs usually when weak points of the coin cause stress fractures, in most cases some form of foreign body gets into the metal mix when the coins planchette is being manufactured. Over time this weak point or stress fracture within the coins material can in somce cases cause the coin to split completely in half like in this example for sale right here!

Exceedingly rare and difficult to obtain
