Last year I was handed down a Morgan dollar by my Grandfather that was collected by my Great Grandfather. I was told the latter stored his coins in paper slips which led to the blotches in the pictures below. My 2 questions are this. What is this considered, corrosion or toning? Secondly, does it affect the value of the Morgan? Any information or opinions are greatly appreciated.   |

I consider that toning. It does not appear to be attractive toning to me.
But someone else here may love the toning! Doesn't hurt or help value IMO.

It's not corrosion. As sui said, it's toning, which is a chemical process in which silver discolors along a color spectrum.

Not very appetizing to me . The paper slips really took a toll on that coin . Can you show us a photo of the reverse ? This type of toning has actually affected the skin of the coin and not in a good way . It's there for ever ! IMHO yes it effects the value of this coin a little .  |

Localized toning. Perhaps a droplet of water was, for a small time, at the toning spots that we see here.
Actually, all toning be it attractive or not, is in fact
a form of very thin surface corrosion, which can sometimes result in very attractive coloring. The corrosion products are usually chlorides, oxides or sulfides.
If the corrosion is very thin, like a film of oil on water, interference of incident light on the coin will result in the perceived coloring.
Much thicker surface corrosion can result in what is known as a 'patina', which can also be visually attractive, as well as actually protecting the coin underneath.
As for eye appeal, beauty is always in the eye of the beholder.

I find the oxidation areas distracting, to be honest.

The areas you zoomed in on do not appear to be detrimental to the grade but the spot at the date looks like it may be worse. However, It is an heirloom so enjoy it for what it is, family history...  |

I actually think that toning increases its desirability.

Take a pic of the reverse so we can see it's condition and if there is a mint mark. That will determine it's value.
