[QUOTE="Publius2, post: 4674379, member: 105571"]To me, I see a well-circulated coin with little or no circulation grime or dirt in the crevices around the devices. This is not definitive in itself. The color is such that normal tarnishing that would occur from circulation as evidenced by a gray-toned color is not evident on this coin, indicating to my eye that it was dipped off at some time in the past. The bluish toning is typical of what is called "album toning" from earlier days where the coin would be stored in proximity to sulfur-containing products like paper, cardboard and glue. In the 19th century where there was lots of coal burning, the air itself would contain sulfur in sufficient concentrations to cause toning. I don't really see the "mild abrasive" cleaning that [USER=101855]@johnmilton[/USER] referred to but he is vastly more experienced than me, so I defer to him. The toning is somewhat "blotchy" and there is an un-toned "halo" around stars, Liberty's figure and some other devices. I have heard this is often a clue to an old dipping and retoning.[/QUOTE]
