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. Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

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. I have too, sometimes it's just worth a shot on a badly corroded coin. You don't have much to lose on a heavily corroded coin. That said, we still recommend a max soaking time of 24 hours per side. |

Has anyone tried Verdi-Care on .500 fine silver coins? VC is safe for ALL METALS. It will remove verdigris from any cupric alloy. Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

So if my coin just came out of a PVC flip do I do all three steps or just the acetone?

Also how fast do you guys go through a bottle of acetone and about how many coins can be preserved?

Depends on the coin. 2 oz in a big shot glass is fine for rinsing a coin, but you may need that much multiplied through a number of iterations if confronted with a serious conservation job. And you don't re-use it. I just discussed this procedure in detail in the 1877 coin thread a couple below this one. Acetone's like $5/qt at Home Depot. |

Acetone's rather a bit cheaper than Verdi-Care, and you might as well use the former to get your best money's worth out of the latter. No use using the scalpel to hack your way into the locked operating room when you have an axe at hand.
