Temperature and the amount of Oxygen that can be bonded by the copper can alter the color. Use a mini-butane torch and you can make a Black pearl on Red ( if you are careful and practice)


There are two oxides of copper.

• Copper(I) oxide (cuprous oxide, Cu2O) , red color forms below 300 C
• Copper(II) oxide (cupric oxide, CuO), brown,black oxide that forms above 300 C

Continued heating to 1326 C results in melting and at 2000C, it boils.

Black and red copper oxides

That would be ANA.. Capital letters.

 

mine s mine looks to be a foreign planchet

 

It's not. It's darkened by post mint exposure to something.. It's a dirty Cent

 

I have lots of dark cents like yours, some even darker. It’s normal.

 

The darker one is from Ugandistan. That's the exact size of Ugandistan planchets.

 

Paddyman, you're frightening the children! Think of others for once!

 

Isn't that the home of the abdominal snowman?

 

Abdominal, lol! My Starbucks Cinnamon Dolce Latte just came through my snout!

 

Hehe.. What.. You've never heard of him?

He does a lot of Sasquats!

 

mine is struck on a red black proof planchet for the cook Islands

 

Okay, then, if it was "struck on a red-black planchet", how'd they get the red highlights on the date, letters, and rim?

 

No it is not. Those Cook Island coins are reflecting a black object placed in front of them
Your Cent is a dirty coin.
Please stop.

 

That is a proof set. Just get the lights and the camera in the correct position and you’ll get the same black background with shiny frosted raised letters, numbers and objects.

As for the cents, I’d like to see the label.

 

Yep, let's see the label on the slab.

 

Look at his picture.. The Cent in question is not even placed correctly within the prongs

Most likely In one of these DIY slabs..

 

I thought of that but I’m sure you know what I was thinking as well.

 

Thanks, hadn't seen that kind before!
