No, it's definitely metal, I've soaked it in acetone to be sure and it came out just the same, it weighs 2.7 grams which shows it's extra metal weight of 00.2. I believe it's a broken coin which got stuck in the press and struck onto a new coin leaving it stamped on the obverse.

I see what you are pointing out, however, when I look at the 4th and 5th pictures you posted, I can see clearly every feature of Lincoln's face (nose, lips, chin) "through" the substance on the coin... that is why it appears to me to be some sort of glue or epoxy and not metal. Weight Tolerance for this coin would be around 2.4 to 2.6 grams, you state 2.7... have you calibrated and double checked your scale? Does your scale weigh to 3 decimal places? Either way, the small additional weight could be accounted for by glue or epoxy, or a very slightly thicker planchet. Additionally, I don't believe acetone removes epoxy, but I could be wrong. Without coin in hand or additional convincing evidence, I am leaning toward this being a clear foreign substance such as glue or epoxy, and two coins having been at one time stuck together then unjoined, accounting for the design transfer that you point out. Just my Two Cents on this. |

2.5 grams is normal with a mint tolerance of +/- .10 grams. Acetone does not remove epoxy type glues. John1 |

Thanks John, that's what I thought... I'm in agreement with your initial thought that this appears to be some type of glue.

I think denatured alcohol can remove epoxy but very slowly. I could be wrong though. Heat is a good way to remove epoxy. A hair dryer on high does the trick to soften the epoxy and then peel it off.

Foreign substance on coin. Try isopropyl or xylene if acetone won't do it. If you do not find a perfect match at varietyvista.com for a DDR, then you have worthless Machine Doubling, Die Deterioration Doubling etc. .See error-ref.com for a list of doubling types and definitions of them). |

Looks like a foreign substance is on the coin.
Errers and Varietys.

It's not glue or "sticky stuff". It's definitely copper struck into the obverse with the memorial on it, broken fragment or plural struck onto the coin, but thanks for all the effort but I'm afraid your all wrong, if you had the coin in hand you'd see it's clearly a foreign material.

Look at this photo properly, the memorial image pressed in to the coin! Glue? Haha, no, absolutely not.  |

Does ANACS still recognize glue as a "Mint Error"?
