I was wondering if this could be an foreign planchet or what kind of mint error this could be.

Side by side comparison, it is smaller than an normal 57-D

It's an "encased cent". It was squeezed to a smaller diameter when a metal ring it was inserted into was struck. In other words, it's not an error.

I had thought of that, I have 3 from a BU roll of 50 of these. Some of them have full rims, this one has it 3/4 of the way around. I weighted it and it weights 3.05 grams. Here is a side view, it only does this 1/4 of the way around the rest is flat like a regular cent.

I see that the edge of the coin is concave in vertical cross-section. This is characteristic of encased cents. No authentic error would end up with an edge like this.

Thank you for your observations, just in case here are photos of 2 more from the same roll, I am particularly interested in the second photos rim.

Deformed, abnormally broad, and sloping "rims" are typical of encased cents. Often the metal is pushed up into a circular ridge along the internal margin of the "rim".
