Either severely eroded dies, or more likely a maladjustment of press tonnage. And only if ruling out post Mint damage.

Curious. I have no idea.
Pretty sure grease

Grease is the word.
Since the rims are fully formed its not a die trial.
It could also be an abnormally hard planchet that did not strike up well under normal striking pressure.
@errormaven is good at distinguishing between these type of errors.
Never heard of an abnormally hard planchet before.
With the tons of pressure applied by the presses they have no issues striking far harder metal foreign items accidentally in the bins.
I would say grease....and an interesting one at that... good keeper... Cheers, RickO
Found this one, looks familiar.
most likely grease filled die
Excess planchet hardness, usually caused by improper annealing, is probably the leading cause of poor detail on US coins. Most New Orleans Mint Morgans with inferior detail can be attributed to poor annealing. The extensive die cracks seen on these are from increasing pressure in an attempt to compensate.
