Please advise! Does this dime have missing clad layers, could it be environmental damage or something else?

 Id like to know about this 1983-D Roosevelt Dime. It's obviously some type of error or damage perhaps. My Internet research leads me to believe it has missing clad layers however, I'm just beginning to learn about coin errors. The pictures accurately depict it's colors and It weighs 2.20grams. I welcome more knowledgeable & experienced opinions.

Environmental damage.

Looks like it might have been buried and corroded. I'm not an expert on modern coins, but I'm pretty sure it's damage, rather than a mint error.

Thanks for taking the time to give an opinion. Guess I'll spend it now!!
