2021P Shield Cent….anybody have any suggestion?

[signofthedimes]

I’ve only been through 5 rolls of my 18, 2021P Shield Cents, and I’ve already come across what can only be described as a built up retained crack which repeatedly strikes the coin as it was raised on the die.

I should clarify, this isn’t the image transfer crack that can obtain the opposite polarity, but an actual crack on the final single working die, which developed after the image transfer. This one would be striking the planchet and leaving an incuse imagery.

Thanks for posting this! My first guess would be that it is a struck through area, where the object creating the strike through shifted and moved, and likely disintegrated over time throughout multiple strikes.

i agree with the above. there are several good examples on 2019 coinage forward, especially the bat quarters and some others with bid obverse progressive/regressive strike-throughs bringing nice premiums. if this is anything other than strike-through, i think it is outside my experience.
