1991 P quarter no visible copper edge? see pic (spelling correction)

I don't know what to make of this. It has rainbow toning (not visible in pic) and no visible copper edge. All comments welcome.

Anyone know where I can find out more about the D/D? I see it in "Coin Prices, 2003" and in the PCGS Pop listings. Is this a recently-discovered variety?
Any information or link would be appreciated...
