Interesting. Does anyone have a mock-up or sketch of a die cap / brockage / counterbrockage in progress/action? It would help me visualize everything that's happening here, and I'm having a hard time wrapping my brain around this whole concept.
No pictures but here is a step by step procedure that should represent the process.
1. Planchet is fed into the coining chamber and is struck but does not get ejected.
2. Another planchet is fed in on top of struck coin in coining chamber, is struck, and becomes stuck to the hammer die. This stuck coin now has a brockage for the reverse.
3. First coin is now ejected from the coining chamber.
4. Planchet is fed into the coining chamber and is struck between the reverse die and the brockage capped hammer die. It will show a normal rev and a distorted normally oriented and raised obv image.
5. As more coins are struck the cap on the hammer die spreads carrying away the peripheral design leaving an enlarged distorted center design. After several coins are produced you are getting coins that look like the OP coin, with a normal rev and only an enlarged image of the central design on the obv.
