1957 penny machine doubling ??

Seems there’s a lot going on with this penny. Pretty sure that’s a little die chip on the bottom of the B in liberty and then pretty sure I see doubling on the year. Not sure what this penny is. And help?

Appears to be machine doubling, but what do I know?

A keeper in my book.

 

The "doubling" an distortion of the numbers and the mint mark were caused by the striking of it, that wasn't on the die.
