Hello, fellow coin aficionados! I've encountered two interesting coins and I'm eager to hear your insights. I've attached images for your consideration.
First up, we have a 1990P penny with an intriguing quirk in the letter "I" of "liberty." I'm curious if it's a case of doubling and would love to hear your thoughts.

On a separate penny, I've spotted some additional material in the word "liberty." Could this be a BIE error? Your expertise is greatly valued in shedding light on these coin curiosities. Thanks for your contributions!
