I suppose you tried acetone? Maybe mineral oil for many days, but you have copper oxide corrosion that has attacked the surface. It may lift the green but there is a high possibility of the beginning of pitting. Ouch! Too bad p, coin had potential.

yeah, I am afraid you may be able to clean off the green stuff, but the damage may already be done.  |

Wouldn't hurt to try Verdi-Care. Might help the obverse, but the reverse is probably already corroded.

You could try the hydrogen peroxide and salt trick.. but the color will make it look pink and scratches appear on the coin. I cleaned this 1919 coin with a process I am trying to figure out. But it makes the coin look more white/gold. I tried it on a couple coins like yours and the results varied from coin to coin. That green stuff could be in there deep and the patina and green together look a lot better then what I've seen (white and green and pink and green). If it was mine. I'd mess with it.. but since its yours, to be honest. I'd leave it alone. I messed with a bunch of wheat's. Some I wish I didn't touch, others so bad its worth a shot. I'm not a fan of the hydrogen peroxide and salt trick by the way. Have you tried soap and water?  |

With the exception of pure acetone, you can't go back once you've tried any other possible solution.

If you have already used acetone, then give Verdi-Care a shot. Maybe even a long soak. From what I understand, Verdi-Care can be removed with acetone if the results are undesirable but, I dont think there's much to lose with this one, unfortunately. It looks like it used to be a very nice coin.  I think this is an improvement:   In Memory of Crazyb0 12-26-1951 to 7-27-2020

I would also suggest to give it a shot with Verdi-Care, look at it this way Devin, you're coin looks pretty far gone but you have a chance to bring some of it back to life  |

Pilcrowcoins: what you made sounds like a mild solution of nitric acid which has similar reactive properties that sulfuric does against copper. Think of a car battery charging the plates inside, they charge/discharge by that same chemical reaction of molecules becoming attached(charge) detached (discharged). What you did was alter the outer layer of copper by mixing the impurity of sodium(salt) with the copper. Hence the pinkish colors and changing of other elements on top of coin if dirty,no telling what those elements were.
Suggest you try hydrogen peroxide and apple cider vinegar in a 50%/50% mix. Or try hydrogen peroxide with baking soda as a soak. Mineral oil works very well on dug coins, like Indian Heads, but have to soak for 1-2 months to really loosen some of that crud.

From experience I don't think you will be able to recover those lost letters on the reverse.

Is Verdi-Care cleaning the coin or just putting a stain on top of the coin?

It's not a stain, it washes off with water. Consider it a conservation treatment. I'd try an acetone bath first to get off any organics, and then soak it in Verdi-Care and see how much of the verdigris you can get off with minimal effort. The coin will look much better, and won't corrode any further.

Your coin looks like it is a detector find . usually you can't help a dug copper coin ,but I agree on the Acetone and Verdi-Care soak .  |
