Found these pics of a coin I sold some time ago, it's a later stage reverse brockage:

Incomplete planchets wanted, especially Lincoln Cents & type coins.

Those are great. Can I get a layman’s terms explanation of what/how?
Just realized that nobody addressed your question. Brockages occur when an already struck coin is struck into the next planchet that is fed into the coining chamber. Typically some part of the design from the previously struck coin ends up visible in the struck through area.
A "full brockage" occurs when a coin adheres to the die and is fully struck into the next planchet. The first coin struck by the obscured die can end up a "mirror brockage". The Buffalo nickel a couple of posts above this is a textbook example of a mirror brockage, where a coin stuck to the reverse die (which was the hammer die on Buffalo nickels), and was then pushed into the next planchet, leaving a perfect imprint.
If the brockage maker does not come loose from the die, it will continue striking multiple planchets, and the raised design will eventually get flattened and distorted from the force of the strikes. The Lincoln Cent I posted is an example of a "late stage brockage", where the reverse image is still visible but is distorted, and the obverse is beginning to show through. Eventually the image wears off completely and you have a plain old die cap.
I hope this makes sense, feel free to ask more questions (or correct me if I messed anything up).

Die struck obverse is a wee bit misaligned & a fin of metal got pushed up K2 - K6 likely due to double thick, stacked blank and struck Quarters in the collar
Wow- that's awesome! I cherrypicked it off ebay probably around 2004-ish. It was in a PCI photo slab (which I think I kept after I removed the coin- it's around here somewhere) and popped up as a newly-listed with a BIN of $250 so I snapped it up. I submitted it to NGC after cracking it out and later sold it on eBay to a prominent error dealer for a nice profit. Glad it found a nice collection to reside in!

I am a big fan of full brockages. Here is the only one that I own. A very iconic design in the Civil War Token series, D. SKIDMORE SENECA FALLS, NY, featuring William Bridgens' eagle smoking a cigar:

Nice errors!
I owned this one a long time ago:
Always enjoy seeing real mint errors with the naked eye and not a scanning electron microscope.

1988P 25c Full 1st strike obverse brockage on reverse
Thanks @seanq!
Do people ever find a series of brockages at different stages of the same stick coon?
Some really great examples of this mint error. And thanks to @seanq for the great explanation of the issue. Cheers, RickO
What is going on with the obverse? Almost looks like an incomplete clip.
The current owner posted photos of your old coin in 2019:

Brockage on dime.
That is amazing, and I agree. You should've kept THAT!
