Is it possible for this type of coin to have 90% silver in it. I found two of these coins 1969 D with 90% silver instead of 40%. Is it possible for this to happen, if it is then how rare is it and how much would it be worth?

Why do you think they're 90% silver? A 90% half weighs 12.5 grams, while a 40% half weighs 11.5 grams. I believe it was more likely to find a 1965 half erroneously struck on a 90% silver planchet from 1964. For your 1969D halves to be 90% silver, planchets would have to be hiding in the mint for five years.
Where did you acquire these coins? If separately, it would be exceedingly rare for you to encounter two.

I would say it's virtually impossible to have a 90% silver 1969 Kennedy half. Why or how do you think it's 90%? I've seen many of those 40% Kennedys with a silver edge (no copper showing). There is a ring test you can try, but the only true test is to precision weigh the coin. It'll be 11.5 grams if 40% silver and 12.5 grams if 90% silver. Edited by batboy

So, you're just seeing all silver on the reeded edge of the coin, right? Like I said, many of the 40% silver halves are like that. I just pulled out one tube of halves and found two 1967 and two 1968 kennedys that had silver edges. Trust me, they are 40%. Weighing it is the only real way to tell.

As some here have already said, many of the 40% halves will show a silver edge rather than copper. Having said that, if your 1969-D Kennedy is 90% silver, it would be worth quite a lot to error collectors. But it must be certified as such via metallurgical analysis. I know NGC offers a test called SEM-EDX which is not destructive to the coin, and probably PCGS does too. Not even weight is sufficient, as the margin of error is too close, I believe.  Kind regards, George |

Misha, the "ring test" is aural, not visual. You listen for a different pitch ring when the coin is dropped onto a counter. Different metallic compositions will sound different.

A sure method would be to melt it with a torch. If all Silver, you'ld know then for sure.  |
