Coin on right is regular coin for comparison. Have a few of those as well in varying shades of gray.  |

 . I am thinking it is just circulation toning. John1  Edited by John1

This coin has seen some circulation. The original mint surface has since been rubbed away, with toning and environmental damage now remaining.

Nothing unusual for a circulated coin.
The more they are handled, the more lustre they lose.

Guess it would be impossible to tell if lustre was worn off or forgotten altogether at the mint. The coin above and many similar ones, (one side or both sides), I have are not even worn to the point you would expect if the lustre was worn off. Text and detail is pretty sharp considering which is why I thought the initial job was not completed.
So it seems like a clad error is more copper or gold colors present than gray?

Are you referring to a missing clad layer? Try using the search box upper left of page and type in missing clad layer. John1 |

looking at the highlights of the peach, ate corn stalks and the banner all of which look like a bit of the silver cladding is showing due to the lighting. If the cladding were gone, you would not see any silver looking metal.

The clad Ni is an Ni not free of oxygen (will cost to much to use in coins production. One was struck, the coin pass in many hands, temperature differences and different environments. The circulation will make the clad to loose the mint shiny strike, the UV and the composition of the ambient air will make become more dull and yellowish. It is the normal low magnetic metal reaction. If was traces of Cu will have the form of small approx. round Cu oxidation which it is not at this color. Hope this explanation will make you understand the metal reactions with the environment. The O and C inside of the Ni will react fast with the Na and C from the air. In the image here I put an Nickel proof who change the color due to the exposition to low frequency UV.  |

I will try to get another picture in the next few days. The light you mention is not showing the coin as it looks. It is all gray without any hint of silver color anywhere. Same goes for the other similar coins I have-all dark/slate gray which just looks unfinished.

Here are the "missing clad" ones in full light:  Here are ones that might be more planchet related with gold tones. They all have reeded edges though so it eliminates the Sacagawea related error. Really hard to get the light to show the tones.  |

If it was missing the cladding, it would be copper coloured and weakly struck. I don't see that on any of your examples.  |

But what about many of these? https://www.ebay.com/sch/i.html?_nk...lad&_sacat=0Many of them look similar to what I have. Copper looking ones might be the classic kinds, but there seem to be variations. Maybe Annealing is the key word for these except the 5th coin that has a more copper look and would meet the clad criteria. Edited by EML Coin Collector

Note the example posted by JimmyD. Note the color? It is not a gray, not a brown, but a red color. That is the color of a missing clad. Also note the strike. They will be weaker because of the missing thickness of the planchet and will be under weight. Yours is just a normal, spendable coin.   |

OK, so all the coins I have are annealing related. That would cover both the fact that there is no lustre and that the detail is still intact. The 5th coin has a very copper look so that would be the only one in the lot that meets clad issue. Image  Desc  Edited by EML Coin Collector
