Silver by looking at the side profile
These are the sides of clad proof kennedy
weigh it
silver clad 11.50 g
CuNi clad 11.34 g
So there are no solid silver Kennedy’s ?
I’ll weigh it when I get to my desk

Yes, for 1999 it would be a 90% silver piece. It would have the same weight as a 1964 Kennedy.
oops 90% is 12.50g

and thanks @ndeagles for the help.

@coinsarefun ... Silver is always good... and silver 'piles' are even better....
Cheers, RickO
the easiest way to check this is a ring test.
Another way to check is put a clad kennedy and this one you posted next to each other. Take a small piece of toilet paper and lay over both. The clad will look gray colored and the silver will look white.

I think my wife buys the thick stuff. Works better with thinner TP. Lol
