I am going to take a guess and say that it will. It's just the length of time is unknown and down to loads of factors such as
handling, storage and the environment.
I imagine if it was stored in a vacuum and kept in the dark it would stay lustrous but what's the fun in that.

All 3 uncirculated. When do I get the prize??

I will have the crown please.

Let's call it VF.
VF with verdigris =
VF with treated verdigris =
VF with no verdigris =
All VF but depends on the eye appeal.
Thanks for the explanation, it's really nice to get such a well thought out response

I take your point the grade of a coin is dependant on the wear of the coin. However in this case the initial assessment of the coin was that it was horrible but with some TLC it's become a much more desirable item.

Sorry Rob but I have no idea what your comments mean?
i was just asking if the process had possibly raised the grading of the coin.

Here you go Ian
Wow, I am impressed. That is a significant improvement. Do you think that the Verdicare has raised the grading of the coin?

Is there any chance of having a side by side before and after picture on the same post. I am scrolling up and down and my brain is not as fast as it used to be.
thanks

Have you tried asking her to trim down her collection of shoes, handbags and pretty things for the house? Then there would be plenty of space for your coins??

I think my M&S underpants have a spell on them. I buy a pack of them and within 3 months they have all disappeared, along with my M&S socks.
Do you think this is a clever trick by M&S or should I be worried about an underwear thief working in my area?

Oh dear, oh dear, oh dear. Paul O don't take It personally, you were looking to sell, offers were made you did not want to take them up and you decided to sell elsewhere. Hope you sold them but that does not stop us making a comment or two.
Grow up and stop acting liking a child. It's just a coin.

Pete, does Dave send his e mail lists later? I haven't had mine yet.
Mike, I had to contact him and ask for the list. I was on his mailing list but did not get this latest one.

It's just my opinion but I believe that if a piece of verdigris is flicked off and there is nothing left on the coin and the coin is not exposed to an environment that encourage the reaction needed for verdigris to occur then it will not come back.
The problem we have is controlling the factors that cause it.
If we think about the above example of a coin with a spot of verdigris that is loose on the surface, at some point the conditions were perfect for it to start appearing maybe it was a small piece of sweat from a finger or moisture from a breath. Whatever it was it landed on the coin and started the reaction with the metal, maybe it was stored in a room with fluctuations in temperature and a spot formed.
Then someone comes along and flicks it off, as long as it loose and comes away clean and completely then that verdigris is gone.
If verdigris reappears on the coin then the conditions for it to be there have not been controlled e.g. Poor handling, storage, temperature etc.

So does that mean it wont come back Ian ?.
I am not a chemist so I cannot accurately say why verdigris appears but I believe it is a chemical reaction between the metal and the environment that it is in. Unfortunately the coins we like to collect are made of the metal that is the most likely to have this reaction, add to that moisture, bad storage and whatever else they react with and verdigris is one of the side effect.
like most chemical reaction if you can remove a part of that reaction it will stop.
If a coin has some verdigris on it and it is continuing to grow then the conditions for it to do so must still be present.
I have read that a small amount of baking soda will neutralise the reaction. If that is the case, and I have no way to prove it other than what I have read, then once it is stopped then as long as the other factors are controlled why should it grow again?
-
As far as I am aware for verdigris to spread the conditions that have caused it need to be present. It is not alive, it's a chemical reaction.
Remove the conditions and it will not spread.
-
You maybe right, silver is alloyed with copper in various ratios. So I suppose the chemical reaction could still take place.
I don't have much experience with silver coins but I am guessing someone on here will have the answer.
-
I hope that I am not wrong in saying that verdigris cannot form on silver.
I believe that verdigris is a chemical reaction between copper and the environment, I an not a chemist so please don't ask me to try and explain it?
Can you post a picture of your coin?

Okay, fair enough. You have this one and the next one is mine.

Yes, but he is offering free postage.

It looks similar but there are differences.
The inscription on the bottom of the box could be interpreted in two ways.
Firstly, it could just be a note that records what took place. The coin was given to someone by L. C..Wyon.
or
It is as assumed, a note written in his hand. Personally I think the signature on the portrait doesn't match enough to prove conclusively

There is some lovely toning going on there. I bet in the hand they look even better. If I had to choose one it would be the 3d
