Hello every one, new here so if I post this in the wrong place I apologize. What I have is a 1979 us penny that has taken a beating over the years due to it's composition. I'm not certain of its exact makeup. I believe it is particularly copper and gold. I came to this conclusion by it's appearance, scratch test specks of gold in 10k acid after all other metals have devolved, weight? The scale I have dose not weight in the 100ths. But it dose bounce back and forth between 3 and four grams. The picture doesn't do it justice but I didn't change anything but the size of the pic. My question is what to do with this coin how to come up with a monetary value if there is one over 1c.   |

 Weight? I think it has been plated after it left the mint.Weight should be 3.11 +/- .10grams. John1  |

Looks like it has been zinc plated, in a shed job.

Have to agree with John and sel.
Plated after it left the mint probably by some student for a science project.

to the CCF First an accurate weight to two decimal points is required. Somewhere between 3 and 4 grams is of no use. Then ask yourself, where would a copper and gold planchet come from? Your coin is not even the right colour. I think that what you have has either been plated or has environmental damage. |

Aa accurate weight might give us important information. For now, I'm in full agreement with JimmyD.

Thank all of you for taking the time to answer. I will serenely get a more accurate weight and pictures that depict more acutely. As far as electrolysis.... in the places that appears to be more gold than copper there's more dents and abrasions. My fault poor photos. I will upload later to day. But if you will let's talk hypothetical and say it is a mixture of copper and gold coin. What would your next step be?

@ona, first welcome to CCF. Second, the final step in this process is to submit your coin to a grading company for verification and slabbing. You are several steps before this in the process though. An accurate balance is an important tool and should be your next purchase.

Let's just start with the weight to two decimal points in grams, please.

What would your next step be? are you asking the same thing twice or just re-stating a question that has already been answered? |

@Onarollman, You do not has to take further steps. And it is not hypothetical talk. 1. Your coin photo I analyzed will be at the end of the post. 2. If you do the test acid and scratch, this it is an old goldsmith test on Mississippi black stone and cyanide nitric acid. 3. Why electrolysis? You want to move some ions from the coin to an plate? and then? Waist time and a lot of money. My CONCLUSION: The coin was plated and then somebody want to recuperate the gold in some empiric and home fashion. In the circles I put you can see the reminiscences of the gold plating. If you do not believe me an chip XRF test will confirm. PS: The surface of the coin show the acid interaction with the core coin.  |

There's no gold on that cent. It's just a school science project.
