I'm gonna try and get a more clear picture of it. It looks like the same metal used on the coin as on the error.

What mark are you taking about, the one on her cheek is PMD the one above her eye looks like it could be Struck Through Grease , would need better pics to tell for sure. |

PMDIf it wasn't done at the mint, then it's not an error. That mark above her eye looks raised. Possibly that scratch on her cheek punctured the nickel/ copper layer causing the steel planchet to start to corrode raising the surface.

I'm only talking about the one on her forehead. I just want to know if that sort of thing could happen at any stage of the coin being made. I tried picking it off but it solidly attached to the coin and at one part it looks like it fades right back into the same level as the rest of the coin.

No. It's rust. Like JimmyD said, the nickel and copper plating was punctured and the iron core is exposed. When something rusts, it expands. These things corrode away from the inside out.

Thanks for your response. So it's not a mint error then? Sorry if I don't completely grasp what is said this terminology is new to me.

Not a problem. We all have to learn and this is a good place to do that. PMD means post mint damage. It was done after it left the mint. If you click on "glossary" in the upper left hand column, You will find a great place to learn terminology. |

 - looks like a plating blister. These coins are struck on multi-ply plated steel blanks. When the plating is compromised, through a scratch or ding, then the inner steel is attacked and rusts... just like the rear quarter panel of an old Mustang...
