"1941 Walking Liberty Half Dollar - Proof-66. what is that dark toning caused by?"

 

 

Oxidation due to exposure at some point to potentially a number of contaminants, including heat, dampness, pollution, etc. The patina of a silver coin is vulnerable to anything that hits it -- BU silver coins should always be stored in dark, dry and cool environments, and away from airborne pollutants -- easier said than done...

Thanks tommyd, I was more curious about the black specks in the center. Its a type of toning I never really come across. Perhaps why I got it for a decent deal.
