An Interesting Example of a Devious Ancient Bronze Coin Manipulation

I most certainly am missing something. I had heard of collectors who make a practice of dipping all coins they get in acetone as a way of removing PVC deposits if any and exposing fraudulent alterations to a coin like painted on patinas and wax fills. We have even seen posted examples of filled sestertii of rare types that most certainly would be worth the effort if the result could pass as a natural surface. The above posts suggests several of you believe that the acetone dip caused the damage to this coin and it had only been acted upon by natural forces. Such a coin would hardly be returnable to the seller as fraudulently altered. It would seem that there is no way of removing RenWax without risking destroying the coin. Is this also a risk if the coin had been treated with something like Verdicare which includes a sealant component? In both cases it would seem that treating a coin for bronze disease would in itself make that coin less desirable than the old way of treating (digging until you reach solid metal even if that was deep inside the coin). I have more than one coin that was done this way but have not heard of people doing it for decades. It seems a lot like the way we treat certain human cancers. Excavate with good 'margins'. Below is a 29 year survivor (or more if the work was not new when I bought it).

What am I missing?

A couple more examples for you guys to look at:

All of these were discussed in the same thread as the O.P coin. All were considered to be cases of restoration/manipulation of roman bronzes with polymeric-material, or even a polymer/plaster blend which could be removed with IPA, acetone, or xylene.
A very interesting discussion.

 

There is a posting in one of the other forums by @Insider where he posted a Morgan silver dollar that had been "filled" in using some foreign material. However, the degree of fine surface features washed away in these photos is really shocking. I have to think about this.
