Post a picture of ANY coin with verdigris. It doesn't have to be your coin, it doesn't have to be one that you think could be conserved.....just any old coin with verdigris. I will pick the most interesting verdigris coin picture as the winner. The prize is one regular 15-mL size bottle of VERDI-CARE™.
It's the green corrosion you often find on copper coins. My definition:
Verdigris is a complex chemical mixture of compounds, complexes and water. The primary components are copper salts of acetate, carbonate, chloride, formate, hydroxide and sulfate. The secondary components are other metallic salts, acids (organic and mineral), atmospheric gases and water. All the components are in an ever-changing and extremely sophisticated electrochemical reaction equilibrium that is dependent on the ambient environment.
I already bought some Verdi-Care the other day. I'm gonna flip my corroded cent and pick a person to donate it to....here goes.......
Aw Geez, the thing broke!
But seriously, I bow out of the contest so someone in need can get that bottle. I've got high expectations for the one coming my way.

I like the short definition... LOL!!!
Jim (A.K.A. Elmer Fudd) Be verwy verwy quiet... I'm hunting coins!!! Good Hunting!!!
Eric,
Even though your coin needs it, I don't think the verdigris needs to be removed to ID it. I am pretty sure it's RPM-052. There are plenty of similar coins from RPMs 50 - 56, but I am thinking 052.
