It can if some of the metal has been eaten away. Your coins seems to be within mint tolerance. John1  |

I was also wondering what exactly is going on with this coin. Is it from outside damage, a wrong or missing planchet? The rim is the same tone as the coin all around.

Each denomination has a +/- of a few grams eg a cent is .13 grams. I don't know what it would be for a half. John1 |

I think it is from out of doors damage, environmental damage from being buried. John1 |

FYI, the reference I found, copied and pasted back then has some discrepancies or typos. Later found the actual 2011 Coin World Almanac specs for Half Dollars to read as follows: 1971 to date (excluding bicentennial 40% silver clad) Composition: 75 Cu. 25 Ni on pure Cu Weight: 11.340 grams Tolerance: +/- 0.454 grams 1976 (similar to 1965 - 1970 40% silver clad) Composition: 40% silver clad Weight: 11.500 grams Tolerance: +/- 0.400 grams Thanks, Doug. PS: I'm debating removing that old reference pending the original authors advice. Some parts seem by the book while other parts I question. Edited by Halo1st

The numbers in the linked tread do have some typos, and they were in reference to specific coins listed in an even earlier thread. Since I can't change the typos it might be best to pull the reference. But I will once again offer to send anyone that wants it a PDF of the tolerances from the 2011 edition of the Coin World Almanac (No typos in it, it's from the book) Just drop me an email. |
