First post and thanks for havimg me. I have searched the forum and Internet with no luck. I am aware of a 71 transition error. While roll searching I noticed this.The presentation seemed more like my late 60s Kennedy's, then others in the rolls, so I weighed it. Thoughts or recommendations ?  *** Edited by Staff to Add Year / Mintmark / Denomination to Title. Titles are Important! *** |

To the CCF Looks normal to me. The tolerance on a half dollar is .26g which makes the maximum 11.60g so yours is within the accepted tolerance. |

The weight and color.As I'm sure you know copper nickel clad is about 11.34 Grams . 40% Silver clad is 11.50 Grams. Also I tested the scale to make sute was accurate.

If it's 40% silver, the edge should not have any copper color, and assuming that is silver. I'd get it into PCGS or NGC to certify.
Unless is silver plated?

The 40% half dollars do have a thin dark edge on them. (very small)  |

@sgtclough -- I also have a half dollar like this. It was the subject of a similar thread a few years ago: http://goccf.com/t/316012#2689730The weights are so close (0.16g) between the clad halves and 40% silver halves that you can't verify one way or the other from even an accurate scale, due to within-tolerance variations. I suppose you could slice between a reed or two w/ an exacto knife and see if you can see the copper core (assuming your coin has no copper core visible), or get an XRF test for a few bucks at a jewelry store. As for me, I'm still sitting on my half dollar (pulled from a roll in the 1980s), knowing it's probably plated but hoping it's an error coin. |

I will have to check those 40% Kennedy of mine, never paid that close of attention in finding the thin copper edge.
Drop tested a few to hear the different tones, but I never find any silver Kennedy outside the minted dates.
