Being new to error collecting, would this be considered an error? There are two nubs of metal, one inside the "D" and one to the right.

Probably just plating bubbles. Poke it gently with a wooden toothpick. If it moves, it's a bubble.

I'm no expert but my thoughts are zinc rot or small gas bubbles. But I'm sure some experts will be able to tell you for sure. And welcome to error hunting. Once you start you can't stop

Our fellow enthusiasts are correct. Gas bubbles under the thin copper plating. Once it separates from the zinc (substrate metal), the zinc is susceptible to oxidation which promotes hydrozincite (a.k.a. zinc rot).
