Interesting 2021 1/4 gold eagle strikethrough progression, questions for the error guys

Recently going through 2021 1/4 eagles I came across the following coins. At first glance I thought I was sent some scratched coins but then looking further it was a strikethrough and I then found another strikethrough in the same place on another coin.

The first strikethrough looks like a ribbon people put on their car windows for various awarenesses like breast cancer, Army, Navy etc. turned on its side. The strikethrough impression looks dark.

The second one contains the ribbon, then adds an extension on to it. The ribbon is no longer dark but the extension is.

So question for the forum and the error guys, what do you think caused this and why does ribbon go from dark to no longer dark?

Images below and I have had the coins encapsulated in a dual coin holder.

Appreciate any thoughts!

    The darker area of the strike thru has remnants
    of the 'struck thru' material. (we don't know what that is)

    The lighter area's are were that material fell off the coin's
    suface, after it was struck.

    I believe if you look at the darker areas closely, you'll see
    the 'stuff' is still there.

    Fabulous photos Todd!
    Great insight Fred!

    When in doubt, don't.

    Nice!

    I am guessing the longer one came first, as it retained part of the thread.

    Thanks Fred. the dark areas looked burnt to me, but it just must have something to do with the material color.

    I’d think the second picture is the first strike through then the smaller the second, only because the “extension” is retained. The next strike would be without it.

    I’m hesitant to guess the material

    Hi Fred. It almost looks like whatever thread created the first one moved and was restruck???

    strike thrus will continue to the next coin(s) struck as long as the foreign material remains on the die. The continuous strike thrus will show a weakening progression until all of the material is no longer on the die or the die is replaced.

    Todd's second coin pictured was obviously struck before his first coin pictured. Again, the number of consecutive coins receiving the strike thru depends on how long the foreign material remains on the die or if the die is replaced.

    Repetition of ignorance is ignorance raised to the power two.

    Correct. All of the foreign material was there for the second piece, which was the first strike, Half of the foreign material remained in that coin, while the top part stayed on the die. It was then struck into the first piece, which was the second strike, and it remained there in the coin. Neat pair.

    Too bad the holder has them in backwards chronological order.
