I noticed when I first got this coin that it had some discoloration on it, i’m not sure if it’s an error or just oxidation? Thoughts?

I’m curious if any of my bills have any cool serial numbers as i’m just starting to learn about the serial numbers.

I’ve been collecting coins and bills and I bought this awhile back, but I cannot remember what it is. I’m not 100% sure if it’s US or foreign
