Hey Thad, on a hunch... You should give this a shot on a toned Jefferson. Not a really nice one, as I'd hate to see one *potentially* get ruined, but I would like to see the effect this has on the surface of a toned coin.

snaz - What kind of toning? I don't think I have any since I don't collect Jeffersons. I pulled the ones I've tested so far out my change jar.

I'm referring mostly to rainbow type colors. I am just curious of Verdi-Care will effect toning. I'm not sure if toning would be considered debris on the surface, or a chemical reaction in the patina of a coin.
Sounds like an interesting experiment. And I only said a toned Jefferson because you can get one for relatively inexpensive.

VERDI-CARE™ should not effect natual toning due to its gentle nature. That type of toning is strongly bonded to the metal and can typically only be removed with strong acid (conversion back to hydrogen sulfide or to sulfuric acid).....which would also remove metal, i.e. the classic acid-thiourea dip.
Nonetheless, if I run across such a coin at a show, I might just pick it up to run a test on. My guess is that VERDI-CARE™ would actually deepen the colors and make the coin look more vibrant. So far, I really like what it does with Nickels. It's hard to capture with pictures, but the surface look a lot better after treatment.
Thanks for the question! Keep 'em coming people!

Airtite stability test: In this test, VERDI-CARE™ was applied and the coin fully dried for 24 hours under nommal room conditions. The coin was then placed directly into an Airtite brand holder. The goal of this test is to see if any residual surface moisture is present. This might cause fogging inside the holder, which could potentially effect the coin. Note: Normally, I would recommend an acetone rinse before putting ANY coin in a holder to remove surface moisture. Here are the initial test pictures:     |

So far so good with the Airtite stability. No sign of condensation after 24 hours. Any apparent haziness is due to the reflection off my light source, in hand the holder is clear and free of water.  Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

Back to a general surface residue test using the microfiber towel for about 30 seconds. This coin had a gummy residue around the rim. It resembled verdigris, but it was not for the most part. There may have been some very light verdigris mixed in with the residue. It's obvious the residue had been there a long time as the surface underneath did not match the rest of the patina. Sometimes removing residues makes the coin obviously cleaned. It can be a trade-off between a "cleaned" coin or one labeled as a "corroded" coin. This is something a collector must carefully consider.  Edited by BadThad

In this test I found a very badly stained, surface residue covered nickel. This test goes to show that VERDI-CARE™ cannot perform miracles! The residue is so imbedded into the coin that virtually NOTHING could be removed from the surface. Note: There's no magic! VERDI-CARE™ can only do so much. This coin would require heavy-duty, surface damaging conservation to save it.  Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

HOLY MARY MOTHER OF GOD! Funny, before I started reading about your product, I assumed that this is what it was for! 2 things: How about some Zincoln tests, and can your product do anything for this guy?  |

Are you talking about the black Mint water stain? If so, then NO, I've found those to be irremovable with anything....that is, without damaging the coin. Overall, YES! VERDI-CARE™ will condition and protect the surfaces of BU coins. Unlike VERDI-GONE™, VERDI-CARE™ is recommended for use on BU coin (all metals). In fact, the main surface protectant ReAcT2™ works best on BU coins since there's more "clean" metal for it to react with.  |

Thad, I have a very heavily corroded coins and some other BU's that have some spots, I also have some corroded sacs that I have found metal detecting, do you think I could have a sample and then show the results here?

Sorry, I'm not currently looking for any more testers.

I should also add, VERDI-CARE™ is not designed for treatment of coins with very heavy corrosion. It is not a cleaner! It is a gentle conservation fluid and surface conditioner for light surface debris and light verdigris removal only.
