Those pennies are 95% copper, they don't contain enough zinc to make it brass.  |

 with buddy, rubbing a coin doesn't remove anything, except for eye appeal. Not sure why you did that. Its just toning |

I don't know why you think that rubbing the coin would remove toning. The metal has changed color. Toning is not the metal changing color, it is the result of oxides, sulfides or other coatings that form on the surface of the metal. Rubbing may not change the color at first but eventually you will wear through that layer and the color will change. |

I don't think this is an alloy issue . Look at the reverse ,half the coin is red, the other half is green, if it was an alloy mixture the whole coin would have the ''woodie effect'' which this coin does not show . My gut says toning possibly from environment . But none the less ; TONING .  |

Does anyone have a photo or reference of a Lincoln Cent that has the same brass/green and copper tone as this coin? |

I do not have any photos handy but I have seen several mid-50s wheaties with similar greenish-yellow toning.

I have collected 45 years and have not seen any lincoln cents "toned" even similar to this. Maybe someone has a reference. As far as woodies are concerned, here is photo of a 1918 woodie from my collection.   |

Many copper coins tone this way in rolls. I have seen many Australian penny's like this and personally I think they look great.  |

Here are photos of the other coin and also a better photo of the coin that has the larger green/brass/copper "tone" The first photo shows the color in bar type streaks. This a characteristic of an alloy coin or most woodies.   |

 Seriously though I will try and dig out a couple of similar examples to the OP's coins that I have stashed away somewhere in this mess that I call my collections. |
