That coin is in no way "stunning."  As for the initial question: Quote:
Patina = Rust And Corrosion? Yes. Rust is corrosion and patina is corrosion. Toning is corrosion, as well as verdigris. It's all corrosion whether by oxygen or not. In Memory of Crazyb0 12-26-1951 to 7-27-2020

spruett001 has said it exactly right.
That is the humble fact of the matter.
Also explains why my personal preference is for silver coins in MS60 or better,
is for blast white over patinated coins.
Nevertheless, I can understand why some prefer nicely patinated coins, especially for copper and bronze coins.
A good patina on a bronze or copper coin can actually help to protect it.

It would be funny if it were from a seller that had no prior knowledge of coins, but when you sell many coins on ebay (11 years now) and state you are a PCGS & NGC authorized dealer, and a member of the ANA it's downright bad and deceptive to describe coins like this as having a nice "patina" I notice it's also the description on most of his large cents, which very few have any sort of a pleasing patina on them.

There's a distinction that should be made here. Rust is corrosive byproduct of iron oxidation - by definition silver and copper cannot rust.
Corrosion describes the reaction of metals to form a more chemically stable form *and* which leads to gradual destruction of the metal object.
In the case seen here, and for many patinated silver coins generally, the surface reactions resulting in the patina protect and passivate the surfaces from further reaction. Therefore the coin shown here is not rusted nor corroded, but it does have a patina.
Corrosion of silver can occur but is generally more obvious and requires stronger chemicals that what you see with more typical environmental-type toning like the coin here
