1864/Multlple Strike Counterbrockage
Counterbrockage
   A counterbrockage error involves a capped die and a previously struck coin. When a capped die strikes a previously struck coin, the obverse design from that struck coin will be impressed into the cap. The result will be a design where the cap face will be an incuse brockage. When a new blank gets struck by this capped die with an incuse brockage image, the obverse will have a raised and spread image from the incuse design of the cap. The below example is an extreme case in which the cap struck 4 or possibly 5 counterbrockage strikes before it was removed or broke away from the die, giving the coin the shape of a bottle cap. It was featured in the 12/01 issue of Longacre's Ledger and is owned by Fly-In-Club President Chris Pilliod.
