I have a couple of Capped Busts that I expect have light garden-variety verdigris. At first I thought it was toning, but the green seems to silhouette or create a 3d appearance on various parts of the coins. Most of the coins have the same problem as this one: Note the greenish hue near the "M" and the "E" ; also apparent on the feathers of the eagle on the reverse.   Would it be best that I soak these coins in Acetone before soaking them in Verdi-care? I want to soak the coins in verdi-care rather than do a spot treatment because I don't want to have to pick at the coin with a toothpick; I fear I could damage the coin if I mess up. After I soak the coins in verdi-care (both sides submerged), how should the coins be allowed to air dry evenly for 24 hours as the instructions suggest? ie. if I dry the obverse face up on a microfiber cloth, the reverse will be face down on the cloth; would this affect the drying process? Sorry for all the questions; I appreciate any insight or advice! Edited by Steelers72

Acetone will help remove surface grime. After an acetone rinse/soak be sure to immediately rinse with distilled water because particulates dissolved in the acetone will re-deposit if not rinsed. I am not familiar with Verdicare. Good luck.
BTW, if you have a hard time locating acetone, it should be the same as fingernail polish remover (but check the label to verify).

Verdi-care is used to remove verdigris on copper coins.
It's unlikely that it will help on a silver coin.
Green on a silver coin is more likely a PVC product.
If so, acetone will take care of it.
And you need to become familiar with the difference between "conserving" and "cleaning".
"Conserving" is the process of removing debris from the surface of a coin that IS NOT a product of the coining metal's reaction with the environment.
The original coin's surface IS NOT changed by the process.
Dirt, glue and stuff like that.
"Cleaning" is the process of removing "something" from the surface of a coin that IS a product of the coining metal's reaction with the environment.
The original coin's surface IS changed by the process. There is metal loss.
Toning, verdigris and PVC damage are the most common examples.

Acetone is a good starting place for silver coins since many of them have been improperly stored in PVC containing holders. The residue is very soluble in acetone. You cannot "over-dry" a VC treated coin. 24 hours is the minimum recommended time. Since the downside of the coin will receive less air, EACH SIDE should be allowed to dry face-up for 24 hours, i.e. 48 hours total. Again, this is the MINIMUM drying time. GOOD LUCK!

100% acetone can be bought at any CVS pharmacy. Look for the CVS brand name on it.

In fact, if you look at the ebay listing, the first coin shown in the pictures is silver (it's also a CC member's coin). Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

Toning, verdigris and PVC damage are the most common examples. Sorry, I don't agree with your definition at all. Conservation is a process that produces a "market acceptable" coin when the process completed. Cleaning is a process that produces a "market unacceptable" coin when the process is completed. Really, it's that simple.  |

Thank you BadThad for clearing up my question with air drying.
Kanga- From the many posts on this forum, I learned that acetone and verdi-care are used as a means to conserve coins. If you research the chemicals in verdi-care, they conserve coins by removing surface growths AND conserve for the future by putting an everlasting invisible -yet protective- film on the coin.
BadThad explained it well in his above post.

It's understandable, since he's the guy who created Verdicare.  Instead of rinsing an acetone-treated coin in distilled water, rinse it in acetone. Acetone is extremely volatile, and evaporates instantly from the surface of a coin leaving no residue. You need not touch a coin with anything after a clean acetone rinse. |

The last time I used acetone, no one mentioned the use of distilled water after the acetone soaking; the acetone evaporated very quickly like you mentioned. |

Just wanted to post an update after I used Verdi-care. I soaked the coin in Verdi-care (both sides) for 3 hours. I later used a toothpick to gently pick around the areas of the feathers and letters where the infestation occurred. It currently is drying and will allow it to dry for 24 hours+ each side. I am extremely happy to say that this coin is finally conserved! I highly recommend Verdi-care to anyone who needs to conserve his/her coins. Thanks BadThad for a great product! Here are some "after" pictures!     |

Will you get back a cleaned detail if you send in a coin to be graded after using Verdi-Care?
