I have had this coin for years and as I'm an amateur I never noticed it until now that the coin was an error coin. I believe it could be one of the few 40% silver clad planchets used from 1965 to 1970 that slipped into regular production lines at the Denver mint in 1971. Please let me know what you think. I currently have it on ebay, but I'm thinking about taking it down until I can afford to get it graded. You can clearly see the error markings around the front and back of the coin. You can also see the reeded edge is two different metals.    |

Compare the reeding to another regular half dollar. You can see it is copper. A 40% silver edge would look silver. I am unsure what is around the edge. Die Deterioration? |

Around the outer devices and rim intrigue me. Can you weight it? Thanks. Doug. edit:  Edited by Halo1st

A 40% silver half dollar edge shows a 21%-Silver/79%-copper band, but there is not much contrast with the 80%-silver/20%-Copper outer layers.

Hi Doug! All I had was a digital food scale. I weighed it and it says 3/8 oz which converts to 10.63 grams.

The edge clearly shows that it was struck on cupronickel clad metal stock. A food scale that only weighs in ounces in not an accurate method to weigh a coin, that must be done with a scale that can at least measure in tenths of a gram.

Thank you everyone for your warm welcome and opinions. I look forward to become more involved and being a part of the community. Still unsure about this one though. I have a lot to learn.

 That edge damage almost looks deliberate and after the fact. |

No, not a cast. I was just throwing it out there because it looks like metal could not fill the mold, if it was cast |

OK, so took some advice and had it weighed correctly and it is 12 grams. What does this mean? Help please.

Kashcox, for me it means it slightly over weight, but still in mint tolerance I believe. I was expecting the opposite. I'm still looking into, but think the dies may have been pitted from rust. Just speculation at this point cause it don't seem to be cast to me, but again I'm a rookie and could be wrong. Edit: meant to ad possible Die Deterioration, but computer wiped it out I see. More later. Thanks, Doug. Edited by Halo1st
