A silver clad coin will have the stripe of copper running through the middle of the edge just like a normal 1971-present half dollar.
This is not always true! I have pulled many silver clad that from the edge looked like a 90%, only to be dissapointed to find out it was a 40%. After you have been handling silver coins for awhile, you will be able to spot them with a quick glance.

You can also weigh them. A 90% planchet weighs 12.5 grams, a 40% weighs 11.5 grams.

Like I mentioned earlier, I have several that look like 90% by looking at the edge, But the date says they are 40%. When I weighed them they came up as 40%. (We can always hope to find something special)

I agree. And also I have seen a 40% that looked like a clad from the side. Another simple way is the drop method. If you have tons of halves simple drop them on one another as you are going thru them. The distinct silver sound will always be there

Crude...but effective! Wonder how many ms65's or higher lost a few grades with this method!

The silver-clad halves usually have a visible greyish stripe or line on the edge which results from the fact that they consist of a "sandwich" of alloy: two outer layers of 80% silver + 20% copper bonded to an inner core of 79.1% copper + 20.9% silver. Variations in the striking process cause this stripe to be more or less obvious in the finished product. Sometimes the edge looks uniformly white, very much like a 90% silver coin. However, I've never seen one with a bright copper edge stripe like you see on the copper-nickel clads.

When in doubt, check the dates, then the weights!

Ok it is a 1968 JFK half.. I weighed it at 11.2.. And now that you mentioned it I took a closer look at the edge.. on one side of the coin you can see a darker stripe. It is inconsistent so from the other side it looks to be all the same light silver metal... I guess I was looking at that side.. So there you have it.. You solved another one.. It is a silver clad like it should be.. maybe next time!

Oh where are my manners... Thank You All of You for your responses.

one more small question.. Do you know of any errors reported for this date? The reverse has a double image on it.. More like a shadow.. kinda.. You can see "plur" stamped on the eagles chest and a star just behind his eye. It is like the whole image is shadowed but a off centered by half..

From my experience, the clad silver is usually more gray then the 90% which is more white, but it is not foolproof.

In my opinion, the ' tissue test' is the best method.

Like any other visual test, is easier when you have a known silver, silver clad, and Cu-Ni clad to compare with.
