Recently picked up a couple coins for my first ancients. At $6 each thought I would take a chance. I thought they were desert patina but turns out they had bronze disease. I tried distilled water then an acetone dip (probably not advised). And finally Verdi-Care. Original coins upon receipt. After distilled water and acetone. 1st Verdi care application (24 hours later) 2nd Verdi care application (24 hours later) Verdi-care seems great considering the condition of the coins. I probably should have not tried the acetone but thought it worth a shot to remove organics. I only applied 1 or 2 drops of VC per side of the coins and it appeared to hydrate the surface while (hopefully) arresting any further bronze disease. Definitely a learning process for this newbie but happy with the product.
@Seattlite86 Here have a look at these results. I have treated 2 us large cents with before Images,need to read shoot them and show you my results.
I also like the results of using this product, it's not 100% but like you said it hydrates the coin surface and once dried is natural to the feel. Acetone works....but better on silver and nickel/copper , I have used it on copper/brass but the results are not as good as one would expect. Not certain how the use of VC would be looked at by TPG. I most probably wouldn't send coins it was used on in for certification in the first place unless a rare variety.
You do understand, of course, that verdigris and bronze disease are not the same thing, right? One is benign, the other "malignant." Verdi-Care is particularly for the treatment of Verdigris. For bronze disease you need to follow a different path involving the use of sodium sesquicarbonate or one of its lesser parallels.
I understand the difference between the two but incorrectly assumed the Verdi-care could arrest the further spread of bronze disease. I think verdigris looks great on most coins but these had obscured features and I was curious how it would all turn out in the end.
Well VC does indeed work very well on coins with small amounts of BD. For a coin such as the OP a mix of soda ash and baking soda may have fared better, followed with VC. I've actually had better luck using VC on BD than I've had treating verdigris on a Large cent.. VC will help with the dryness of an ancient after using ash & soda.
I agree with this, vc works ok for minor surface bd and as a follow up when more drastic treatment has been completed. It tends to darken some patinas and make coins more shiny, which can be good or bad depending on the coin.
