Country Of Origin? ~ PMD Or Error?

Here is another coin that I do not know the Country of Origin. I also purchased it as a die struck error, and after pulling this (and others) out of years of storage, and a second glance with the passage of time, may now believe it can be some sort of Post Mint Damage, and if it is a squeezed job, I see no sign of a second image on either side...

I posted 7 photos for closer examination, and if it is believed to be a PMD, please give a brief description on what details jumped out at you to reach that conclusion...
