2019 P War in The Pacific Quarter oddity

Hi all, it's been a while!
My 3 guesses...in order.
Environmental/PM damage, struck through grease, or die adjustment strike.
Opinions?

I think the term is 'sweated',
but in any case, it's PMD

Those surfaces occurred after the
coin was in circulation - not an error
coin, I'm sorry to say.

 

Thanks Fred, I figured it was something post mint.

 

Looks like it got stuck in the washing machine for a while. No error I can see.

 

acid damage??

 

I like the "Washington Machine" Damage! @john65999

 

Definitely damaged

 

What would be the point of "sweating" a clad coin vs. gold/silver coins?

 

Looks like the coins we sand blasted when we were teens with access to a sand blaster. So your first guess is the correct one.
