I didn't know that was a Mint water stain - so I learned something new today (always good). So at least I don't have to worry about it spreading and I could just preserve the coin as is before storage.
So, basically, it lays down a thin protective coating. So, if you treat a coin with light verdigris, but small traces remain afterward, will it "quarantine" the cancer to the current area and neutralize it and avoid future spreading? I guess I'm asking if it would impede the growth of verdigris?
Are there other coin cancers we should know about?

The active in VERDI-CARE™ (ReAcT2™) will combine with the metallic elements in the corrosion essentially halting it as long as the coin is protected from air and water after treatment. The answer is YES, it will impede the growth. All corrosion should be of concern to collectors. All coin metals can corrode, just in different ways.

Checked the IHC tonight, this picture is how the coin looked before conservation and 8 days after. It sat under normal rook conditions with periodic turning. Note: Coin looks a lot better. It seems to have darkened slightly compared to the 24 hour picture.  |

Since I got this for $1, I figured it'd be a good test piece.   Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

Some thoughts and I'm sorry they're not more positive but I think they're honest.
I think I would be initially alarmed at the increased light reflection index on the surface of a coin. In fact I don't know that I'd like it at all. That 93 dollar went from the flat gleam of silver to being what I'd expect from an aluminum alloy. Is it inherent in the product that the refraction index has to be so high or is this something you could change? Flatten it out somehow?
Very interesting thread btw.

My Two Cents on tests I have preformed * Copied from my site * Initial Observations -------------------------------------------------------------------------------- Initial application of product on coins is complete. The coins are currently undergoing the 24 hour air dry process. Before-and-After pictures will be added once individual tests are completed. Product does not remove adhesive residue (not an intended use) Product seems to work very well at removing Verdigris Product seems to return "luster" to coins Product seems to work extremely well on silver coinage Product seems to work extremely well on "Golden Dollars" (SACAGAWEA and PRESIDENTIAL) Product seems to remove permanent marker from coins very easily.(not an intended use) |

Ugly - Thank you for your comments. I appreciate ALL input.
Remember, my main goal is to compete with COIN CARE, which is an oil, and which give you a very "glossy" surface. Oil treated coins have a very glossy look, but VERDI-CARE™ is not nearly as glossy. VERDI-CARE™ is designed to condition the surface. I would HIGHLY recommend not using the product if this is something you don't want to see. From my experiments so far, the glossiness subsides with air exposure and is subtantially reduced with a water rinse. Fully rinsed and dried coins have just the slightest gloss.
Thanks

Excellent coretj! I'm glad to hear you've started testing. You covered some things I didn't even think of. I'm looking forward to your pictures and impressions!

So far, I am very impressed.
I wasn't even trying to remove the marker, it was just on one of the coins. But it came off like it was water paint.
I can't wait for the drying time to be up so I can take the after pics and post them... I think you are going to like test # 9.. but it won't be done for 8 more days :)

A quick test before bed. A somewhat dry looking 1939 Jefferson. Rubbed on microfiber towel for about 30 seconds, patted dry and took picture.  |

Tonights test, 30 seconds rub using microfiber towel. Coin has light to moderate, almost heavy in spots, verdigris.   |

Back to the corroded Jefferson to check how it's doing after air exposure. I think my white balance or lighting was off a hair, no detectable change to my eye. The corrosion looks to be contained and inactive.  Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

Rechecked the 1972 Lincoln with heavy verdigris that turned black (cupric oxide). The patina appears a bit darker but that could be my photography....I'm no pro! Left pic is after application and right is 9 days later.  |
