Based upon your name and no pic, I'll assume you're talking about a Peace dollar. Sometimes these spots develop because of the rinse @ the mint. Sometimes they're hazy, either way they do occur on Peace dollars and cannot be removed even with dipping. These spots are more prelevant in some years then others.
That's my educated guess as to what you're referring to.

I specialize in Wisconsin currency! Looking for information on WI national banknotes. Census stands at 12,318 notes.
**"Wisconsin National Bank Notes - 2nd Edition" is out!!!" Only $20PPd!!!
That's my educated guess as to what you're referring to.
