Five years ago, I found a 1983 DDR in a roll of cents. Unfortunately, I lost it shortly after that. However, a couple of months ago, I rediscovered it in near plain sight in my bedroom. In 2012, it had some slight green growth on the obverse. Now, that has gotten worse. Does anyone have any ideas what this is? Verdigris? And how would I go about getting it off, or at lease stopping this so I can keep this in my collection for years to come? Pics aren't the best, considering I took them through a five-year-old 2x2 while in a rush. Obverse:  Reverse:  Edited by The Silver Searcher

That is a prime candidate for verdi-care if I ever saw one.

BadThad's step plan, but think the deed's done. After attempting put in airtight, not 2x2 or flip

I would do an acetone bath, then a Verdi-Care treatment. When all said and done, put it in an Air-Tite. Good luck!  In Memory of Crazyb0 12-26-1951 to 7-27-2020

Okay, thanks for the responses everyone. Can someone elaborate on how it works, where I can get some, and what it will be expected to do?
I'm away at school now, but I'll plan on ordering the stuff so it arrives when I do on my next visit home.

I got my Verdi-Care on ebay. It may seem a "Thad" pricey  but, that little bottle goes a long way and I think it's worth it for your DDR and anything else that may come up. It acts as a corrosion inhibitor and protectant. So, if the coin has verdigris, the treatment will halt that process and protect against future corrosion. It may not remove all signs of past corrosion as the metal has already been affected. I suggested an acetone bath first to remove any organic gunk or debris that may be present so the Verdi-Care can be fully effective. CCF member BadThad is the creator so, you can always PM him for further info. Hope this helps. In Memory of Crazyb0 12-26-1951 to 7-27-2020

If you use acetone only use 100% pure,not the nail polish remover kind. I think you should PM BadThade before you do anything to that coin. John1  |

I agree, it looks like a good candidate for Verdi-care. For the record, here is Bad Thad's polarity ladder, which should be followed first. |

Thanks for this post. I've been having fun going through thousands of Lincoln Cents that I had quickly looked at, not realizing that I might have been passing over errors and varieties. But a few of these have the green crud on them, and needed to find out just how to remove it so I can view the coins more clearly. I've seen Verdi-Care advertised, but have always been hesitant to clean/restore coppers, well, any coin for fear of botching the job. So I will purchase a small bottle of the product and see how things go. Since these are free coins I am finding, if I goof, not really a terrible thing. I can always keep the coin in my collection, as an example of the error or variety.
I've also heard an acetone bath is a fairly safe way to remove all kinds of gunk. I will purchase some of the pure stuff, and also some distilled water to bathe the coins in after the bath.
How should I dry the coin afterward? Will dabbing the surfaces with a soft cotton cloth, something like you clear your glasses with be OK? Again, thanks for this thread.

I personally do not use distilled water but, if you do, use a soft cloth (like a microfiber glass cleaning cloth) and dab the coin and then air dry.
The same goes for Verdi-Care. After treating the coin, dab it with a cloth to remove excess solution and leave to dry for about 24 hours. I leave them in a folded over cloth to dry.

spruett001, thanks for the advice. I have plenty of throw away cloths to use due to my astronomy addiction. Always needing to clean lenses, or cameras. I will experiment on a common coin first, to learn how to perform the task properly before moving on to coins that might have more than face value.
