If ya submit to a third party grading service a properly conserved (not cleaned) coin (e.g. Verdi-Care), does the third party grader care? Does it get a details or cleaned annotation? Is there a "conserved" annotation?
I've seen "improperly cleaned" annotations on slabs. Is there ever a "properly cleaned" annotation? or is it just "cleaned"? So the "cleaned" annotation (which is not "improperly") means "properly cleaned"?

The proper use of products such as acetone or VerdiCare to "conserve" a coin would not normally affect a TPG opinion. They are simply looking at what's in front of them and have no idea what you may have done. The coin will be judged on is merits in-hand. |

I thought the TPG's use a "sniffer" to detect chemical cleaners? John1  |

There are lots of threads on this, but I don't have the time to search for them and link. Check in the Main forum. But the overall consensus is that acetone will not affect a TPG opinion. OTOH Verdicare can affect the grade. There are Verdicare coins in problem free holders, but just from my own experience, large cents I've used verdicare on have an altered surface and color/look, and I would not even try to submit a Verdicare coin to a TPG, I'm sure it would come back details. I will be submitting some acetoned Morgan silver dollars in the future and am confident they will grade ok, but will know 100% for sure after I get them back. |

My experience with LWC in 5 TPG submissions after VerdiCare has been entirely different - not a single details return. |

Ok, so I'm assuming that you washed all of the Verdicare off before submitting. I can see that, it washes off well. I tend to treat some of my large cents, and leave some Verdicare on so it has a little bit of a wet glossy look. Those are amazing stats, 5 for 5 after Verdicare, congrats.

Thanks guys. Acetone quickly evaporates and leaves no part of it behind. From the Wizard Coin website about the two-stage Verdi-Care system: "Closest to the surface, the ReAcT2™ ingredient forms a semi-permanent bond with metal. This layer provides heavy-duty, advanced corrosion protection and is only molecules thick. It is completely invisible and will last virtually forever." Apparently, acetone will take off the "top" layer left by Verdi-Care, but not the layer bonded to the metal.
So something is left behind by Verdi-Care. I kinda like the idea of that something being there to protect/conserve the coin. But do the third party graders care? Apparently not, at least for some LWCs.

Keep in mind, every coin is different. You cannot make a blanket statement about conservation results with TPG's regardless of the treatment/method used. Even NGC rejects coins from it's own conservation services (NCS) - it's an unpredictable thing. A coin can be rejected for a multitude of reasons, the worst offender is what usually appears on the slab. With EVERY COIN, slabbing is a roll of the dice. I've seen hundreds of coins that looked fine and original to me get rejected. I've seen questionable and obviously cleaned coins slabbed. It's literally all over the map! My advice is not to concern yourself so much with the results. Do your best at the conservation method of your choice and submit. If in your eye, the conservation turns out subpar, don't submit and consider buying a replacement. It's really as simple as that.  Good Luck! |

They only use their sniffer if you pay extra for the service. However, they might analyze high-dollar coins on occasion.....but they definitely do not sniff every coin. |
