US580.)ONE OUNCE PURE SILVER 1992 COLUMBUS COMMEMORATIVE DOLLAR: genuine silver dollar issued by the US Mint and only 106,000 of these were minted. This is a cameo proof specimen and is so graded by the PCGS firm. One full ounce and 38mm wide showing frosted proof details of Columbus holding pendent, his ships behind him and 'COLUMBUS QUINCENTERARY 1992'. Reverse has a spectacular split view of Columbus's ship and the Space shuttle. With 'ONE DOLLAR' on back and 'UNITED STATES OF AMERICA'. Comes in clear lucite holder and has been graded as PRCAM 69 by the Professional Coin Grading Service (PCGS). It's PRDCAM graded which is Deep Cameo Proof, meaning that there are frosted and contrasting mirrored fields on both sides. With an ounce of pure silver (which this coin is) being valued right now at $33.00 an ounce this proof coin is a bargain at the asking price. On the reverse of this lucite holder is a hologram which is designed to prevent counterfeiting go the case. Flawless++++
