This is not entirely correct. They are still clad with an exposed core composed of 79% copper and 21% silver. Because of the way the planchet is cut, the core may sometimes be obscured by metal flow from the upper 80% silver layer.
Thanks for the correction jbuck. I didn't have any on hand to look at and was going from memory. The ones I had in the past didn't have a copper band on the rim but after looking at some Google images, I see that some of them do have a faint copper band. |

There were no 90% blanks in the mint in 67... only some off struck 65's Are these 90% 65's considered error coins? How common are they? |

Not common at all, as far as I know they are pretty valuable, how valuable... someone here will know.

So unlike the copper 1983 Lincoln Cent which no one has found yet, there are some rare 90% 65's that have been found. I guess I should check the few I have for the heck of it.  |

I have found 40% halves from roll searching because the previous searcher saw the copper band and assumed it was not silver. He or she had even marked the edge with a black marker just like a bunch of other halves in the box, so that's why I look at every single date. The quick eyeball test doesn't always tell the story. :) |

ok ive read throught this entire post and I have a question regarding the 1967 90% silver Kennedy half dollar. now ive checked everything I could and even checked the weight which is considerably heavier then the other half dollars I have. but just shy of the 64 90% I have. can anyone explain this to me because I'm getting the feeling it's the real deal. I'm not sure how to load a picture up here but I have 3 clear pictures of it. please help |

Wow, this is one of the most impressive necro-bumps I've seen yet...nearly 8 years! And the last post (before yours) was from a member no longer with us.  For uploading pictures, check the "Tutorials" button on the top of the screen. Hoping you do indeed have the real deal!  |

You say your coin is "considerably heavier", what is the actual weight? From that we will be able to tell if further tests are needed.

Remember that 40% silver Kennedy halves can weigh up to 11.90 grams and still be in mint tolerance. If you have a calibrated balance that weighs a purportedly 40% silver half at over 12.0 grams then you have something to investigate. |
