Well, I was in for a treat one afternoon as I visited a pawn shop and found these nine one troy ounce South African Silver Krugerrand Commemoratives. They commemorate the minting of the 1 oz 22k gold krugerrands from years 1967-1983.
These have a highly mirrored background like a proof coin, but are described as BU, beautirul uncirculated.
For those thinking of investing in gold and silver, the time couldn't be better. Gold is low at about $1600 an ounce, silver still below $30 per oz.
