allranger Pillar of the Community United States 1391 Posts	Posted 08/20/2012 9:50 pm I recent got several coins from the Netherlands and Denmark that were minted during WWII and the metal is zinc. They are in mostly good condition but a couple have some white gunk or corrosion on them. I have some Verdi-Care and was wondering if this would help the coins at all? Has anyone tried this?

sel_69l Bedrock of the Community Australia 21788 Posts	Posted 08/20/2012 10:29 pm I think that Verdi-Care may be a good choice, because it would be mild enough in it's action, however, zinc is a lot more reactive than copper, so you will have to watch what is going on very closely. Remember, Verdi-Care was designed for copper and bronze coins. Experiment with the lest valuable of your zinc coins first. Be very careful with the storage environment with zinc coins.

I do not think VC will help Zinc, but I could be wrong.

BadThad Bedrock of the Community United States 19949 Posts	Posted 08/24/2012 3:11 pm Zinc corrosion (zinc oxide) is nearly impossible to remove without damaging the surfaces. VC will not be effective at conserving such coins because it is very gentle. However, the ReAcT2â„¢ ingredient will stabilize the corrosion and stop it where it is. Lincoln Cent Lover!
