Pennies unproperly coated or PMD?

I'm still new to this, so please bear with me while i try to figure out how to take better photos and the cropping done better, i found these 2 pennies last time i went through a 50 dollar bag, and i've never seen anything like it, it doesn't look like they were taken to a grinder, it literally looks like they just weren't coated properly, maybe even not struck properly, but i'm no expert, thanks for your time and input, its much appreciated. I hope these photos are at least good enough to get some input, the edges are completely devoid of copper, and i've never seen anything like them before. Thanks for taking your time, i hope the pictures are good enough. I

PMD. They have been worn down to expose the zinc core. Spend them before they disintegrate.

 

Somebody gave that one a good scuffin'!

 

Hey Vizzura . How are you , I see you have another coin. It's just PMD , I agree with the experts .

 

A Dremel with a buffing attachment could be the source of this damage. The whole of the coin would be plated, not randomly and only the high points as you have here.

 

For anyone that doesn't know what a dremel tool is . JMO :

 

Unfortunately those are DEFDAM..
Definitely Damaged .. As stated by the others.

 

Great photos but as previously stated, they are damaged. Definitely spenders. Welcome to CT.
