Featured Strikethrough Progression on 2021 Shield Cent's

    Got a pretty interesting phenomenon to share today.

    I recently picked up a box of 2021 Shield Cents to search for new errors and varieties. While searching the first roll, I came across a pretty nice strikethrough error, which was exciting! What I did not expect to find was the progression of this strikethrough on other shield cents within the same roll and next 2 rolls. I know that there are such things as early, mid, and late die states for many doubled dies, but I did not know a similar thing existed with strikethroughs as well. Below are the examples the best I could photograph them as well as a small description of each one. (Photos should be in the order as listed)

    1. Early Progression: Very minor strikethough error on the back of Lincoln's neck as well as in front of his mouth and below the beard.
    2. Early-Mid Progression: Strikethough becomes more pronounced in front of Lincoln's bust as well as on the spot on the back of his neck.
    3. Mid Progression: Major change with a larger strikethrough going towards the date touching the 2 and barely touching the 0. The other strikethrough areas have also grown, but not as large.
    4. Mid-Late Progression: This example is very similar to the mid progression example, but on this one, the strikethrough is slightly deeper into the penny as well as moving closer to the 0 in the date.
    5. Late Progression: The strikethrough is much deeper into the penny than the previous stage, and has now taken a part of the 2 and first 0 off on the date. The smaller strikethroughs around the bust is now much more pronounced than the previous stages.

    I also tried to get a picture of each penny entirely, but if they are slightly blurry, my apologies. Stage 1 is not there as a full example as I can't upload any more images haha. It may be difficult to tell the depth of stage 5, but it is definitely deeper than the other examples.

    Figured this was too cool of a phenomenon not to share! I have also never witnessed this first hand, but rather only heard about it. I am not sure if this is uncommon to have the examples of progression or not, but I still consider it really interesting!

    Very Nice strike through haven't seen or found one on any 2021 coins.

    Not 100% sure that it is a lamination. I'm in the strike through camp.

    A lamination is a planchet flaw. How would it "progress" from coin to coin?

    I originally thought strikethrough as well, but thought it looked more so like lamination with the earlier stages of it, so I went with that. I could be wrong though

    It may be a strikethrough error then, but it is pretty clear that it is growing with each example. I changed it regardless to what the common consensus is

    A strikethrough is usually caused by some piece of material that falls onto the planchet and is struck into it by the die. For there to be a strikethrough progression, that same piece of material would have to fall onto the next incoming planchet, and then the next, and the next and so on. I don't know what the anomaly is, but I don't think it is a strikethrough progression.

    That is fair. I would assume it is possibly grease build up on the die due to the shape of the indentation. I only labeled it as a progression as it becomes deeper into the cent and further down towards the date as the examples continue. I may be wrong, but that is how I understood it

    You may want to consider reversing the progression order. The Debris that stuck to the die and caused the abnormality on the coin would reduce in size with each consecutive strike.
    This would be the opposite of the action of a die crack/chip which gets bigger as it progresses.

    Granted, there could have been some portion of a device that became filled and compacted with grease and debris, but it would have to fall out of the device (dropped element) and onto the field. It would still fall away after being struck by the die unless it was a retained strikethrough which remains embedded into the surface of the coin.

    But a strikethrough damaging the die too will repeat. For the chunks it took out of the die raised areas will manifest on the coin. Are you sure all this is sitting down or are some areas raised?

    I may be wrong, but I'm pretty sure that the hardened die steel is too hard for any piece of compacted grease and dirt to damage it.

    Certainly those aren’t candidates. It depends on what it is.

    Adding, this is parallel to the strong die polish lines. We see how that material scratched into the die surface. I wonder if they’re related.

    After thinking about this, I would agree, if it was grease or some debris that caused the strikethrough to happen. It would make sense that it would slowly begin to be removed by all the planchets passing through the punching die. I can't seem to edit the post, but thanks for pointing this out.

    Yes it would seem that the area where the indentation has some spots where it is raised. While the raised areas are within the indentation, they are still there in some spots. Your guess is most likely better than mine on what it could be.

    The thing is it is a stain. Because otherwise the whole thing would be raised because it had to be recessed on the die to manifest as a crack on the coin. In other words, the die won't just impart a flat line to the coin. For this to be a die crack the whole thing has to be raised. Does that make any sense?

    Interesting, I have not paid much attention to the newer coins, but I am going to start.

    So it was a stain on the die punching the planchets? I guess I am not following as I am confused on why a stain would leave a deep impression unless I am misunderstanding what a stain is in terms of coin errors.
