I've only had experience with one coin in which it started getting a bad case of PVC all over. Was able to remove it but it also removed some of the originality it had. In general though, I avoid coins that have been cleaned, whizzed, etc

PVC residue remains on a great many coins, today. Unless a collector reuses an old flip, the contamination most likely occurred many years ago. Storage will determine how badly the coins react. Here's an informative article ...

I cleaned this 1860-S dollar to remove a post. I tried a soldering iron first with little success. Multiple applications of silver test solution eventually broke the silver solder down. But there is still an unreactive glob of gold solder covering 186 of the date.

Cleaning:-Who-And-Why?

Before cleaning the post covered DOLLAR. It wasn't a thing of beauty to start with, but it's a $100 coin. A good one to practice on.
