Personally, I'd continue with diluted Verdi-care. Appears very unstable in this state.

Glad I read this, I thought they stopped making Verdi-care.

I'd continue with diluted Verdi-care I've never actually used Verdi care, It's a bit expensive delivery wise to the UK. I have seen a lot of images, before and after, using it and the results look quite impressive. I might buy a small amount to try it out if it's really worth it? Kev.

You could soak in a solution of sodium sesquicarbonate for a few days at room temperature to remove some of the green material.
Formula for sodium sesquicarbonate solution:
10.6 g of sodium carbonate (washing soda) and 8.4 g of sodium bicarbonate (baking soda) dissolved in 100 ml of distilled water

Here is the coin after an overnight soak as suggested. It's back in soak, only removed it to take half way pictures. Quite impressed with the mixture, coin in hand you can actually see some silvering showing. Obverse Before and after :-   Reverse Before and after :-   Sorry about the different picture sizes.

You have to be careful and watch the coin as sodium sesquicarbonate will strip the patina.

Very nice results... I have quite a few that need cleaning in this way but will wait to see how this one turns out. You have some really nice coins Victor and I always like seeing them when you post.

I have taken the coin out of soak and dried it then brushed it off with a very stiff toothbrush. I didn't want to risk harming the coin. So here are the last two pics of the result, I must say, I am pleased with how it has turned out.   |

Nice work @met. The remaining green stuff seems to be very adherent which I think is good news.
