So I have been reading on these two products and have a few questions? First which is more effective at preserving coins that have verdigris or have been in no Mylar flips? Second how long would you leave an average coin in acetone and how often would you have to change to acetone? Lastly could any of these two products possibly harm the coin or its surfaces? Also is there a reputable dealer on ebay that sells 60ml bottles of verdicare? Thanks for the help! |

Use Verdi-care for the verdigris and conservation. See Badthad to purchase . the acetone is used for removing oil, fingerprints, gum, etc. I wouldn't leave the coin in acetone for more than 24 hours. ( NOTE it evaporates very fast ).

Has anyone tried Verdi-Care on .500 fine silver coins?

You should really define what type of coins your attempting to do anything with. Some may not be suited for any type of cleaning at all. Others may well need that.

Cents in flips with verdigris just use Verdi-care. not acetone. You'll get to know the difference between the two.

John I've left coins in Verdi-Care for weeks at a time with no damage from the VC. I can't imagine it would ever cause harm but maybe Bad Thaddeus can weigh in.

Acetone is a completely different animal than Verdi-Care, and is used for entirely different reasons. It's my advice that a collector wash every single acquisition in acetone (or xylene, slightly lower on the polarity scale but of equal effectiveness for the task of removing organic contaminants). That includes specifically coins which will then be treated for the things that Verdi-Care is made for, which have nothing to do with organic contaminants. Of course, every rule has its' exceptions, and for xylene/acetone, the exception is this: Evaluate what the acetone might remove, and decide if the resulting coin will look worse than before, or cleaned. When crud only partially covers a coin, the uncovered surfaces age at a different rate than the covered ones and once the crud is removed you might end up with a coin having "clean" patches which clearly show it to have been treated with something. That is a worse outcome than leaving the coin dirty. Acetone is incapable of interacting with the metal of the coin, except one very narrow case scenario involving copper, sunlight and the presence of water vapor. But with acetone being as volatile as it is, I'm not using it in direct sunlight anyway. And it mixes well with water, so I'n not allowing water around it either. You can leave a coin in acetone forever and not worry about it, although obviously the length of time for any given soak relates to the seriousness of the crud you're removing (and evaporation). The longest I'll leave a given soak is 48 hours, and that's only in serious cases of PVC contamination. It's immediately followed by a rinse in fresh acetone to ensure that nothing the previous soak removed (and the suspended in solution) has been redeposited on the coin. Anywhere you can buy Verdi-Care puts money in Thad's pocket.  He's "q3excessive" on ebay, and you're buying it directly from him there. |

So let me make sure I understand this.
Use the acetone to remove organic material(Gum, tape, glue, new fingerprints) and use Verdi-Care to get rid of verdigris or a coin that came out of a flip that contain PVC.

Close...
Use the acetone to remove organic material (Gum, tape, glue, new fingerprints), including a coin that came out of a flip that contains PVC. The PVC caused residue is chemically organic.
Use Verdi-Care to get rid of verdigris only.

When I buy a coin and than dip it in acetone should I do 3 baths for each coin? or just do a quick rinse? If you only do a rinse do you reuse the acetone or no?
Sorry about all my questions I just want to make sure my collection stay preserved.

You always want to rinse in fresh acetone, never reuse it. Whatever is removed from the coin ends up in the acetone. As the acetone evaporates that junk can redeposit onto the coin.

However, I personally prefer acetone as I feel it's a bit more effective AND cheaper. Since PVC is both corrosion and residue, VC is a good solution to follow-up acetone with when you have a PVC problem but certainly not required. I've conserved many silver coins with acetone and does a wonderful job. |
