    I guess it's all in the eye of the beholder..
    I agree. Platinum has more secular and diffuse reflectance than silver. It is brighter.

    Today, the platinum to silver ratio hit its lowest point since September 2013...slowly trending down...nice.
    looking for PSR to drop to 50:1, then make a swap from silver back into Platinum.
    C'mon silver! add a few dollars to POS!
    C'mon Platinum! drop another hundred dollars!

    Polished Platinum reflects about 75% of visible light, Silver reflects about 95% of visible light and is significantly higher than any other metal.
    Of course silver tarnishes. The very best mirrors are surfaced with silver.
