A 40%-silver clad coin (1965 - 1970) should weigh 11.50 grams. Your 1971-D copper-nickel clad coin should weigh 11.34 grams. Look at the edge of your coin for the clad layer, or if you cannot tell, take it to your local coin shop. Bonne chance.

Here's a little better picture, sorry I hope this helps. Also I can see the layering on the edge but I understand that a 40% coin has a center that is 90% copper and only 10%silver, so on a coin like that would I still be able to see the layers or sandwiching?

Two options on your Clad Half .
Certification at a TPG or for 10 bucks XRF at
a Coin shop or jeweller .
Good luck , but I don't like your chances .

to CCF. Going by your pics it does not look silver. Options: tissue test,TPG,or XRF. But as I said it does not look silver,so I am thinking it is not.

The outer layer is .800 silver and .200 copper in inner core is .209 silver and .791 copper . You should not be able to see the "sandwiching"

After I looked, I guess you can see that a little

Most digital scales aren't very accurate and wear, and other things can change the weight


I do not agree. Most digital scales are quite accurate and can easily be checked (calibrated) with coins of known weight.

The ring test (by ear) in my view is far less reliable than a weight test-too subjective. There are free Apps you can get to check the ring tone with your phone-and can easily compare with a known 40 % silver coin.

I see no point spending money on an XRF when there are better free options to use at first.

dropping coins to hear a sound? Is that a good idea? what about possible damage.

Better photos needed--sharp/in focus, high resolution--both sides of coin and an end-on shot of the rim. Thanks.

If you have another Kennedy half, the best as John1 suggesting a tissue test, will not cost you anything except a single ply of tissue.
Verify whether it passed or not.
