Could someone share with me why a copper-clad coin's edge might be yellow instead of the more typical brownish/reddish color. I was looking through a bag of Ikes and one stood out like a sore thumb. It's glossy looking (almost looks like someone polished it), letters are extremely sharp. At the same time, it has a lot of hairline marks on it. It's a 1976 Type 2, no mint mark Ike. I believe it's type 2 because the second "S" in States does not go half way up the "E" like in a type 1. Any thoughts are appreciated.   Edited by Learning About Coins

Sulfur in the air can turn silver coins yellow. (even cupro-nickel coins can also turn as well. depending on the area you are from)

I was recently using a borrowed scale that I had to return. I did buy one and it's in the mail. So sadly, no I can't weigh it right now. I did the tissue test and it does not look silver to me. I know there were copper-nickel clad proofs in 1976 but all with "S" mint marks. This one has no "S" mint mark. |

Just a heads up. If you bought a small scales I would discard the cheap batteries that came with them and place some premium batteries in from the start. I bought a cheap electronic scales and the batteries started leaking almost immediately. Almost ruined the scales. I have not had the same problem with Energizer. Still Lookin

None of the Ike dollars had a mint mark from Philly. So it is a Philadelphia business strike coin. |

Thanks for the head's up on the batteries.
Is it possible someone was able to clean it in a way to make it look like a proof coin. It looks like a proof (though I'm not believing it, if only because I'm not that lucky). The 1976 no "S" mint mark proof is one of the rarest modern age non-error coins (was a test run and only one known to survive; the rest were supposedly destroyed). If they did a test run for the silver proofs in Philadelphia (we know they did), might they also have tested the copper-nickel proofs in Philly as well? That'd be a coin I could see someone wanting to fake.
But the yellow reeded edge makes me wonder if the coin has been manipulated in some way.

Maybe a dip (cleaning) would make the edge look yellow? You can make a coin shiny like a brilliant proof coin by polishing it but that does not change the other aspects of a real proof coin. John1  |

 with the polishing hypothesis. If it is a Philly business strike, which it has to be, then it probably turned yellow in the 1970s type mint set cello. Polishing will make the coin bright while the yellow oxidation remains on the reeds. How do I know? Because I've done it.  |
