Why would a 40% silver coin not *sound* like a silver coin?

    Please listen to the sounds in this video.

    1st is clad.
    2nd is 40% half that "sounds right".
    3rd is a 1967 Kennedy half, but... Sounds... Weird?

    It weighs 114g, just like a "normal" 40% coin. It has a heads and a tails. The rim looks like you would expect on a 40%'er....

    114g?! I know you mean 11.4g.....well the best I can tell you is to flip them with your hand/fingers and listen. That sounds like a magicians coin to me.

    11.5g is the target for a 40% and 11.34g is the clad weight. Yours is right in there.

    Is the rotation correct, 180 degrees etc?

    You have to inspect the edges real good.

    However - I have never heard of a silver one yet..

    Good catch on the weight. I hate that my digital scale has an extremely small decimal point!

    Rotation is correct. Could it just be coated with something?

    Weight can be off a bit, yours is close enough.

    Rotation good is a good thing..


    Coated? Well if you flip it as you would a coin you should 'hear' the silver. When you dropped it on the video I was 99% sure it was a magicians coin as it has NO ring at all....

    The harmonic resonance is off, which clearly means its a voodoo coin with a hex on it. Better get rid of it immediately. Bad coin! Bad!

    Sorry, I realize my post is not at all helpful.

    Sounds like a job for Geordi La Forge! Or at least Scotty...

    There is a simple explanation that would explain the sound. The 40% coins are essentially clad coins and if the bonding process was not completely perfect, the sound would not be right.

    I really does. Kind of freaks me out.

    Of all the proposed solutions presented thus far, that would make the most sense. I'm no expert, but I can't see any seams, and the weight is correct.

    Maybe I'll take it to my LCS to get their opinion. I'll hang onto it for the next time I'm at a coin show.

    I'd go with Doug's explanation, an internally flawed planchet.
