Hi,
I am here again with an other question about the coins weight.
Every body knows that from 1965 to 1970 the weight of the US Kennedy half dollar with %40 silver should be 11.5g and copper- nickel coins after 1970 should be 11.34g.
But, I have a 1968-D Kennedy half dollar with 11.28g!? even less than copper-nickel coins.
What do you think about this coin?
I am waiting to hear from you.
Thanking you.
With regards,
Habib.

I added the new information to my weight chart to put both figures on one source:

Hi,
Thank you for your kind suggestions. But if we consider all these options, then how we should be sure about the weight of our coins? For example, the difference between weight of copper-nickel half dollar and %40 silver half dollar is only 0.16g, so if we consider this weight tolerance(0.26g) and apply it to our coins, then we will have copper-nickel coin with a weight ranging from 11.08g -11.6g, and its weight may cross %40 silver coin. And similarly, the %40 silver half dollar coin will have a weight ranging from 11.24g- 11.76g!? and I know this is not not acceptable. Because, We see lots news from PCGS about the error coins which have only 1/10 of gram or so differences with normal coin, so under this circumstances what criteria do they take in account?
with regards,
Habib.

You can also try the tissue test to see if it is silver or clad.

But they weren't using anything but the 40% silver coins during that time. They didn't start using the clad in 1971. What does the edge look like? Is there any double lines on the rim of the coin. (Some coins are altered to make them into magician coins) If you see a double line like this on the rim, it maybe an altered coin:

Hi every body,
Thank you for all your kind suggestions. As I mentioned previously, this Kennedy half dollar is dated 1968-D, so apparently it should be %40 silver coin with 11.5g weight, but as you will see in attached images, its weight is 11.28g and this weight is for copper-nickel coins not %40 silver coin!
The edge of coin is silvery not reddish, which means it should be a coin with silver content.
An other thing, the copper-nickel Kennedy half dollar is introduced from 1971, but the date of this is 1968, it can not be copper-nickel.
Please let me know your kind suggestions.
With best regards,
Habib.

Second opinions are always recommended. Rookies thoughts!
Two sides to every coin. The edge makes three.

The weight of your coin is within tolerance.
