I have never sent a coin into a TPG after using acetone. So I could not tell you on that question. I am sure if you sent it in with PVC on the coin, that would cause a details on the slab. Here is the Walmart link. ( I use the first can, blue and orange) It is in home improvement, not beauty. http://www.walmart.com/search/searc...&_tt=acetone |

It would kill me to have them grade it improperly cleaned by using a solvent I'd be more worried about the ding at 9 than acetone. Given the wear to the coin I think they would let the ding pass. |

thanks for the link GR!
jack- thanks for the assurance about sending it in after acetone. I just bought some PVC-free mylar flips and I am going to dunk this in acetone when I get it. I'll let you all know how it goes.
Thanks again

Let me point out the obvious for anyone that might have missed it. If it's PVC & you do nothing before you send it in to a TPG it will come back as a details grade. |

BadThad- if it is verdigris, what do you recommend I use to remove it? Is there a verdigris-removing solvent that will not harm the coin like acetone?

Quote:And I have never sent a coin to a TPG that hasn't been rinsed in acetone first. Me too after getting a couple of PCGS submissions body bagged in the early days for PVC residue. That was a hard pill to swallow at $30+ per coin. Always use pure acetone never nail polish remover (It can have oils and fragrances in it not good for coins). You should be able to get acetone at any hardware store in a quart can for under $5.00 Acetone should never hurt a coin, you may need to let it soak for 24 hours or longer on really crusty dirty coins. On circulated coins I sometimes use a cotton swab lightly to help dislodge any residue that won't come off, never on an uncirculated coin though, don't want to leave any hairlines on a nice reflective surface! Your CBH looks like it may improve with a quick dip, it doesn't look like it will need a long soak. A minute or two probably will remove any PVC traces. Don't be to afraid to try, acetone is really not going to do anything other than remove surface contamination, it should never change the color or remove toning (unless the toning is artificial). On copper coins it can dry out the surface and that is why many EAC collectors will treat their old coppers with another substance after the acetone soak like "Blue Ribbon" (no longer in production and very hard to find today). Silver and gold should not have that issue. You do not need to rinse the coin after the acetone bath, it will evaporate by itself completely. Water, even distilled water can leave moisture on the surface, and that is bad, acetone will take water residue off as it evaporates. P.S. BadThad is the creator of Verdi-Care the best stuff next to acetone for coin preservation out there, I'd take his word over mine or anyone else's on preservation. He is a GOD in that field!

Thanks everyone for taking the time to explain for me!
Now, would it be a good idea to put all my capped busts in acetone even if they don't have pvc on them just in case they do?
I appreciate all of this help, it really means a lot!

BadThad's creation is the only appropriate solution for a numismatist facing verdigris on a coin. I believe this coin must be treated as a PVC byproduct infestation first; it looks more like PVC than verdigris and PVC is the more pressing possible problem.
Get this coin into acetone, stat. Take the one day it'll involve to research this forum for the appropriate use of acetone; we discuss it frequently here and I (among others) have expended significant verbiage concerning the safe usage of it. Acetone is a substance which is only safe for usage by an informed user; the casual practitioner stands a good chance of both wrecking his lungs and burning the entire neighborhood down. Don't be that guy.

Thanks for the info. I've used corrosive chemicals without problems as I've taken Organic Chemistry and lab during college back in the day; but this usage when it comes to coins is something new to me. I've always viewed putting coins in any sort of liquid as cleaning/damaging but the members of this forum have proven to me that acetone is safe.
I'll be using a mask and goggles but now my one last question is once it is done soaking (I'll keep it in there for an hour or two- no harm in that) how should I go about removing the coin from the glassware I will be using?
I read up on this forum and watched some videos online, but I really do not want to be using tweezers or porcupine quills (haha) to do this. Would simply taking the coin out of the glassware with my hands and placing it on an old, but soft, hand towel to dry suffice?
Did anyone on this forum make a demonstration video on using Acetone on coins?
I appreciate all the help and advice.

Acetone will take off the luster if you allow it to stay in too long, so even with it take care.

Absolutely wrong. Completely mistaken, and a disservice to spread such nonsense. Acetone is chemically incapable of interacting with a silver coin. |
