I was just looking on the Internet and saw this black spot on the right of the coin which was on an auction months ago. Is the black spot an evidence of old cleaning? How can a black spot cause on a silver coin? And do you think this coin has been cleaned a while ago? Thank you for everyone's input.  Edit 1: upload reverse in case if anyone is curious.

Are those hairlines on the obverse actually on the coin or just on the slab lens? If they are on the coin I would say that it has been improperly cleaned. Notice how they cross the devices and the fields. There is wear on the obverse when you observe the flat spots on the face, breasts, and arm so I think at best it would grade AU and possibly AU details improperly cleaned.

I would say almost certainly that is evidence of cleaning.

The black spot could be from the black tarnish that silver gets over time and an attempt was made to remove it - harshly

What did PCGS grade it? It looks like serious scratches in that area, like removed graffiti.

I originally thought it was circulation wear and the black spot was a result of coin ding into the coin field. The spot is actually reflective when moving into different light angle. Now I don't know anymore.   Edited by tintin02

Well be glad it got a straight grade. (which is good) But if the black is shiny, it goes along with my thought that it is silver tarnish.

Is it possible if someone could explain how tarnish could appear on a coin and could it lead to a details grade when it appears on the coin?

The coin does not have an original surface. The coin was most likely dipped to remove toning and the black toning spots on obverse and reverse did not come off with the dip.

Terminal black toning etches/damages the surface of the coin that can lead to a details grade. Below is a 64 silver Kennedy half dollar before with black terminal toning and after a dip. Note the damaged surface from the terminal black toning. Terminal black toning  After dip in eZest  Edited by Slider23

This one was lucky to get a straight grade, but the Coin, not the holder.
Pass for me.
