    Hmmm, just thought of this. The telltale sign that the knowledgeable
    detective observes that give this away as a fake is the slight bit
    of fuzziness, like tiny beads, wherever there are sharp edges or
    points (that plus the suspicious heft). This is caused by a
    phenomenon of electroforming, that being that there is more
    electrical activity in those areas hence a faster plating buildup.
    The way to avoid this problem is to plate, then strip, then plate, in
    a sort of 3 steps forward, 2 steps back strategy, but in this case,
    the forger isn't quite savvy enough to think of this.
