    It's a genuine mis-annealed or
    improper annealed planchet.

    There's one easy way I could tell
    it's genuine - can anyone guess
    how?

    copper bleeding through the clad layer ..

    Close, but the copper core is there anyway;
    it's not bleeding thru any clad layer.

    The appearance of small cracks on the coins surface (obverse and reverse)?

    No, getting colder.

    I'll post the answer in about
    5 minutes, if that's OK

    It doesn’t bead water on it’s surface as it appears to be porous

    It's a result of a loss of protective atmosphere or being stuck in the annealing furnace for a prolonged period of time, or both.

    I could immediately tell it was a
    genuine mis-annealed planchet because:

    Every single 'mis-annealed' coin that someone
    has shown me at a coin show, or in an email, that
    turns out to be environmentally damaged or played with,
    has a darker duller surface than it should have, AND
    every single non-error has the same dark color
    on the reeded EDGE of the coin.

    See the edge photo (#3) - it looks like a normal
    BU Quarter - the copper core shows a nice normal
    red color - that's because although the planchet
    itself (on a genuine mis-annealed planchet)
    would have the dark color on the smooth edge,
    once it's struck in the collar, and ejected, that
    dark color is removed from the reeding due to
    the ejection of the now-coin from the collar.

    (I could also tell it's real from the surfaces themselves, -
    although mis-annealing leaves a range of 'darknesss',
    seeing the reeding as a normal red copper color is one
    of the keys to know it hasn't been played with)


    Hope this helps - it's a good authentication point
    to check, if you're not sure of a 'darker' color coin
    is truly mis-annealed/improperly annealed, or has
    been played with after the coin was in circulation.

    Although most of the 'full' dark
    planchets are uniform as to the
    darker color on both sides, there
    are some that show a normal
    surface on parts of the coin, due to
    how it was laying in the annealing
    drum when it dried.

    That's a good thing to look for, but
    there are exceptions.

    ....as opposed to a coin that's
    been 'played' with, which will
    have the darker color ON the
    reeded edge.

    Closing the office now, will see
    you all tomorrow morning.

    Swan,

    Based on the edge of the coin in your link above,
    it looks genuine.
