Verdigris Naughtius ?

The green spots don't have the pale powdery appearance of active bronze disease. I'm thinking that there's nowhere near enough green on this coin, actually - it looks overcleaned to me. The entire coin was probably covered in stable green patina, until someone cleaned it until the only green bits left were protected in deep recesses where the cleaning couldn't get to it.

The red stuff is corrosion, but not necessarily "bad". Trying to remove it will probably only make the coin look worse. I suspect it was either hiding under the original green layer, or some of the green stuff turned pink when it was hit with whatever process (chemical or electrolytic) that was used to clean this coin.

As noted the best thing now would be to just seal it in something.
Almost all gone now.

Waxing was once quite common among coin collectors; before the invention of airtight plastic coin holders it was the best way of sealing a coin away from the atmosphere. "Renaissance Wax" is a modern formula which some ancients collectors apply to cleaned coins, mainly as a preservative to prevent active bronze disease forming. It also enhances the appearance of certain kinds of patina.

I don't use it myself, but then I don't do much coin cleaning.
