A counterbrockage is one of many forms of capped die strike. So saying the coin was struck through a die cap wasn't wrong, it was just non-specific.

Because it is struck through the extra thickness of the die cap, it enlarges the devices. That is what we are seeing.  Note the reverse image on the bottom of the die cap. This shows that the Memorial is being enlarged when struck onto the next coins. |

That's not correct, Coop. A counterbrockage is generated by a brockage on the working face of the die cap. Anything that bleeds through the floor of a die cap from the die itself will be normal size.

Not quite, Coop. The OP's coin was struck by a die cap, just one with a spread-out brockage on its working face. The working face of a die cap can carry a raised design, an incuse design (i.e., a brockage), a mixture of raised and incuse elements (generating a brockage/counterbrockage error), an off-center design, or no design at all (i.e., a uniface die cap). Other patterns exist, or could theoretically exist.

Coop
Cent is struck and remains in coining chamber. Planchet fed in on top of previously struck cent and is struck, This creates a full brockage. That full brockage sticks to the obv die and the other previously struck coin is ejected from the coining chamber. As subsequent cents are struck that capped die creates counterbrockages. As striking continues that full brockage spreads becoming a die cap and the counterbrockages it creates become enlarged such as on the OP coin.
That sound like a correct sequence Mike?

I think I have it, or a headache. How many strikes will show a counterbrockage before it goes away? Just one or more? Here is a mid stage CB:  Edited by coop

The number of counterbrockages a single die cap will vary. Factors include metallic composition, whether the original brockage was normal size or expanded, and whether one or both participants (cap and planchet) are partly or completely confined by the collar. In the case of a zinc cent die cap striking planchets completely out-of-collar from the get-go, probably only two counterbrockages can be produced before the working face of the die cap is battered smooth.

Thanks Mike. That was what I was look for. So these are pretty rare?

Centered, mid- and late-stage counterbrockages appear with regularity on ebay. They generally sell for less than $50. Early-stage and first-strike counterbrockages are hard to find. Partial counterbrockages are also scarce. On U.S. coins, counterbrockages of the reverse design on the reverse face are vanishingly rare, although they can occasionally be found among foreign issues.
