1991 D Double Die Reverse...such Thing?

Hello all,

First off, I hope you all had an amazing Thanksgiving with those around you!

I've been looking through my pennies that I've been saving for a while now, being that I had recently started using my 60x loupe and after searching through 100s of pennies, I think I found something interestng...a 1991 D double die reverse...or possibly split copper plating?

I am thinking it may be split copper plating, but there is more than I usually see on other examples.

I rarely see this much on other split copper plating coins as mentioned, but may be wrong.

Here are the photos I took. (tried my best to take the best pictures possible)

I see some the doubling on the " ONE CENT" and a bit on the "UNITED"

What do you guys think?

Would love to hear all of your opinions.

Thanks in advance.
