I am 100% certain that there is no copper on this coin I have beaded on her a jewelry eyes an no copper can be seen. Mark Twain probably would find you a fool. You must get satisfaction Out of putting down other people. I would guess you are the tip of person how picks on the handicap trying to look cool an for praise, and validation from the people you think are your friends. When in reality they think your a idiot an talk behind your back but to slow to realize it. So they just use you till your no good to them. Sincerely Crowcoins Report this Post to the Staff
Cujohn Pillar of the Community United States 7174 Posts	Posted 07/22/2023 2:29 pm Ok I see in the new pics that it was a reflection off the surroundings. The surface is to dull to have been a unplaited planchet. If it was unplaited planchet it should have a smooth shiny surface. I think the copper was removed with chemicals.

silviosi Pillar of the Community Canada 6244 Posts	Posted 07/22/2023 9:02 pm The second photo show some Cu. Could be the light? It is a possibility. Now for chemically remove the Cu, Please all who state this just give the solute will do THIS? It is easy to say chemically remove but with what?. The electroplating it is very simple and easy to understand. The Zinc it is negative and the Cu it is Bi. So the positive ions of the Cu attach to the negative ions of Zn and let the negative Cu Ions outside. Like this the coin will be always negative. To remove the Cu you has to be Einstein to discover the way to move negative ions to positive ions and so broke the stability chains of the elements. Here the photo which show me CU Report this Post to the Staff

Petespockets55 Pillar of the Community United States 5775 Posts	Posted 07/23/2023 09:07 am The coin is underweight and doesn't exhibit any mint luster. Both are signs of a coin where the copper plating was removed. Words of encouragement are one of the major food groups. We need to consume them regularly to thrive and grow.

Petespockets55 Pillar of the Community United States 5775 Posts	Posted 10/13/2023 08:04 am One thing to be looking for is mint luster from being struck by the dies. I don't see mint luster and do see what appears to be staining. I'm in the PSD group. Thanks for posting an interesting coin. Words of encouragement are one of the major food groups.
