Kennedy Halve dollars

What is the allowable weight variance on clad Kennedy 71-present? I tried looking it up but not seeing anything about tolerable weight difference. Thanks

11.34 grams...

 

Did you actually read the question?!

 

1964 12.5 grams +/- .259 grams
1965 - 70 11.5 grams +/- .4 grams
1971 - date copper nickel clad 11.34 grams +/- .454 grams
1976 40% silver clad 11.5 grams +/- .4 grams

 

Is this some form of error hunting?

 

Good information. Thanks.

 

There are errors of wrong planchet. I have seen many '71s that with a little wear and toning were hard to tell whether they were silver or nickel clad. A gram scale will easily tell the difference.

 

yes. I found no place that has the tolerance differences.

 

So you really believe that the weight of a half dollar can be off by 11.34 grams either way?

 

ok thanks everyone I found a 77 that looked a little thin to me but no wear on it that weighed right at 11 grams and my scale is pretty accurate but wasnt sure on weight tolerance, looks like it is within tolerance though.

 

If coins are missing the rim due to either wear or a weak run through the upsetting mill, they will visibly "appear" thinner than coins which have a full rim.

 

dude let it go. not in the mood to fight at all. no... it was the weight it is supposed to be... but you could not tell that ? geez get a red book dude.

Yeah I won't be winning any spelling bee's or grammar awards anytime soon.

 

Great answer .. sounds like an ~ +/- 4% Standard on most modern coins. Most likely more than most scales can discern regardless of Digital Display

 

Don't go slow. Don't go fast. Go half (halve) fast.........
