1998P 10C clad layer

[Shleppodella1]

Missing clad layer or frostbite?

[Zimmy]

Hard to tell from the picture but it may be just some sort of environmental discoloration. It the area affected raised or incused?

It's incused and there's some bumps on the cheeck and an edge were the clad meets the coating along with rustish color from I guess air & CO2 exposure plus there's a missing flap by lower lip. Out of curiosity what environmental damage would cause this? It has some medium bagmarks and minor mint luster left. I can post additional photos if needed? I didn't think that it was warranted for this because it was confined to the main focal area on the obverse. I'm going to start posting obv/rev automatically, so that way it's like you have the coin in your hand.
