New p: Verdigone candidate?

Here is a Woods' Hibernia halfpenny, Harp left, 1722. I really like the obv. detail. There are patches of verdi on the reverse. What do ya'll think?

I don't think conserving it would hurt. If you do please post after pictures.

Thanks

 

Your not going to hurt it......It looks to be a candidate, but please be careful and try it in something common and not valuable first. And YES, please do before and after pics.

 

This would make an excellent example

 

I would not mess with the coin.

Destroy Lincoln's, not history.

 

Lets re-phrase that

" destroy verdigris, not history'

 

Search back for my thread where I used it on a large cent. The verdigris here appears to be "deep pitted", so it will be rather difficult to remove it all, and there will be pits left where it has. You should plan on this occurring so you can make the determination. BadThad has a thread some place where he talks about selective use of Verdigone ( using it only in certain areas an not just dunking it). I would think about using that method near the rims and then a short dunk of the whole coin to reduce the pitted areas a little with out changing the color of the patina ( watch it carefully and often). For me this would leave a little green in the pited areas which I think would be acceptable to me. A rinse with water and then acetone and in a stable holder should keep it that way. I don't think it is possible to remove all of the green without changing the color noticeably, but it can be conserved for the future. IMHO.
Verdigone is safe when used as directed and minimally.

Thanks for the suggestions-- it isn't a very expensive coin, I would just like to reduce the extent of the corrosion a bit-- I am thinking of selectively applying Verdigone to the green areas with something like a TB syringe that will allow very precise placement-- of course this would require quite a few applications due to the small volume of solution involved-- and a little judicious pickwork with a thorn or something-- and I think a short overall soak makes sense too. I'll do pix as things progress and post them-- there is a lot of interest in Verdigone, and I think the more experiments we post the better we will understand its pluses and minuses.

 

That is some very heavy and deep verdigris. Honestly, I don't think you'll have much luck with VERDI-GONE™....but I could be wrong. It would definately require some physical action. VERDI-GONE™ is mainly intended for light to moderate verdigris.

 

Good point. I intend to find out if repeated, small applications followed by mechanical debridement will have the desired effect.
