Error question

That wacky nickel got me thinking about something that I haven't really understood. What is the difference between a brockage and a capped die?

Edited to correct:
In layman's terms: A brockage is a coin struck with another coin- not rejected from the die, striking a third host planchet. A capped die, I believe is close to the same scenerio but with mulitple strikings thus causing a mushroom affect to the newly struck planchet.
A broadstrike is a coin struck out of collar.

Isn't the coin struck out of the collar a broadstrike?

Brockages and what you call "capped die" errors are essentially different stages of the same error. A die cap is formed when a planchet doesn't eject from between the dies after a strike, but rather sticks to one of the dies. After the cap is formed, it will impress the exposed design into the next few planchets it strikes. For example, the nickel you linked to was struck by the reverse die and an obverse die cap.

Only the first couple of strikes from a die cap will create a brockage, as the design on the bottom of the cap is quickly obliterated from the pressures of striking coins. The nickel above was probably the second strike from the die cap. Eventually the bottom of the cap will thin out and the design on the die will begin to bleed through. Strikes from this late stage create the error you called a "capped die" strike.

Obviously, this makes true brockages much scarcer than capped die strikes. They are also harder to authenticate, as brockages have been faked by grinding off the face of a normal coin and impressing another into it.

HTH. I'll be happy to try to answer any more questions you have about this or any error.

Thank you! That all makes perfect sense.


What would you call the coin that was stuck to the die doing the striking?

This is normally referred to as a die cap and can be anywhere from near normal, if
quickly dislodged, to just a ring of unidentifiable metal. There is a indian cent die
cap which looks much like a thimble and a clad proof half die cap that looks like a
small bowl.

A brockage is the coin struck by the capped die.

Ok, but lets examine what this new term actually means. Planchet, an unstruck blank tat has been through the upseting mill. Hammer, the upper die or the die that is not restrained by the collar. So a hammer planchet would be a planchet resting either on top of a previously struck coin or on top of another planchet. Of course once it is struck it is no longer a planchet. It would then be either a brockage with the incuse image being that of the hammer die, or a coin with an indent strike on the anvil side.
