Just found this on an old 1900S Morgan. Entire coin is like this, even in the nooks and crannies, hair lines, crevices, etc. EVERYWHERE. Not visible in hand, but pops with at 15X. Thanks in advance.  *** Moved by Staff to a more appropriate forum. *** |

Can you post a photo of the whole coin unmagnified? Will be easier to tell if that happened by someone cleaning the coin with something.

Here are full obv and rev. It doesn't look whizzed or dipped. Downsizing here takes away from the "look", like what's posted in the first pic on this thread. When in hand, it has a flat, smooth sheen across its entirety versus having the cartwheel affect when lit. Very strange    |

Maybe an attempt at cleaning with an acidic substance? Kind of reminds me of acid treated nickels, but not sure how silver looks after that type of treatment.

Cleaned with an acidic dip of some kind which was not removed; may also be due to ground effect, e.g. the coin was a metal detector find which spent some time buried. The porosity as seen under your scope makes me think a detector find is more likely.

 Looks like a metal detector find. Errers and Varietys.

It is absolutely not a detector find. Silver comes out of the ground almost exactly as it was dropped. With the exception of long salt water immersion.
This was a long acidic soak.

With the exception of long salt water immersion. even then the surfaces wouldn't look like that. Take the silver coins found from the wreck of the SS Republic. After all that time submerged in the ocean they still look great today. |

Agreed, Mark, but they had exceptional treatment. I'm talking about single beach finds that do get a gritty appearance.
I just get tired of hearing that every colored coin is a detector find.

True, I didn't give that consideration. |

If I remember chemistry and electricity right, that may be a product of acid, such as nitric acid. A compound made, rather byproduct of the combination of acid and silver is the volitle silver nitrate, which is used in ammonium nitrate which Little Abdullah in his Garage uses to make boom-boom. The process of acid and silver does discolor and leave residue, think lead plates in car battery (turns from grey to black and back) charging/discharging in an acid medium.
