A friend found a 1971-D 40% Kennedy half in a roll.Any one have an idea how many were struck and what the value might be? |

How do you know it is 40 percent?

Technically none. Silver halves officially ended in 1970 but were picked back up with a 1976 set. And they continued again with the silver proof sets in 1992

I am trying to look for one or see one for a long time. What is the weight?

I would love to see a picture of this one too. I am sorry to hear that he shaved the edge to find out what it might be. In any case a picture could be worth a thousand words.
Thanks,
Bill

Are you sure he filed the rim and it was silver? I have never heard of a 1971-D silver clad so what he is likely seeing is the copper-nickel mix. Under certain lighting conditions, it doesn't look all that different from the silver clad halves from 1965-1970. |

In theory, since 40% silver clad planchets were used in 1970 at the Denver Mint, It is theoretically possible that a leftover planchet was struck in 1971.

Coinhunter,it is without a doubt a 1971-D silver clad Kennedy half dollar.I have never seen one either but acording to the Red Book,a few were minted as well as the 1977-D silver clad half.I'm trying to get him to have it certified but he is reluctant to have it leave his sight. |

My appologies....there were some minted by accident. Trying to find mintage numbers right now. If it is genuine it will carry a high premium...but because he filled it then it will drop the grade a bit. Here's an old post that unfortunately went no where with the same coin http://goccf.com/t/19232Here is a 1977-D on a silver planchet. So far I can't find any proof of an actual 71D in existence. It is believed to be nothing more the a rumor http://www.bowersandmerena.com/auct...g=&lotno=674Edited by GO

Cutting it was a pretty dumb move when all he needed to do is weigh it That has the potential to removed hundreds or thousands of dollars of value if genuine- it is now a damaged coin  . Saying "without a doubt" is a pretty bold statement to make without having weighed it or or having it independently verified. No one will consider a rare error such as this as being the real deal without a third party grader authenticating and certifying it. |

You'll never find mintage numbers on an error. Might as well stop looking.
Filed part of the rim on a suspected high value error coin? What was he thinking? Couldn't he just weigh it or listen to it and tell the difference?!?
At any rate, if he filed part of the coin off he destroyed most of the value it would have had. That's assuming it's really what he thinks it is.

Wow that is cool and I didnt know that! Time to get out the Red Book and do some more learning! |

The first thing he should have done is weigh it. The second test should be a specific gravity test, which should be done by someone experienced with the technique. As far as filing the edge, it won't provide conclusive evidence. While the 21% silver core of any typical 40% silver half will have a gray color, if you cut into it with a scalpel it will show a copper color that is barely distinguishable from a copper-nickel clad half dollar.
As far as the general advisability of an invasive test on the edge, I confess to having done it on occasion. It's unobtrusive and has saved me the hundreds of dollars that it would have cost me to conduct an SEM/X-ray analysis. It has revealed very clever counterfeits and also unsuspected compositions. It should be done under magnification and involve the removal of as little metal as possible. On reeded coins I use a scalpel to shave one side of a reed under a microscope. No grader would ever pick it up.
On error coins, severely damaged specimens that are scraped, gouged, bent, and even folded over are routinely given grades of MS-64 and higher. So a tiny bit of edge damage won't make any difference.
While an invasive test is a last resort to obtaining an answer, I value certainty over a pristine edge.
