Potosi Mint; Assayer Diego de Ybarbouru (Y). Philip V. PCGS VF-35. This Cob displays matte surfaces with taupe toning. There is much peripheral flatness, but the obverse center offers a clear denomination, mintmark, and date. The reverse is also quite flat, presenting the castles and lions as abstract shapes, yet it too preserves a fully readable date. A nice problem-free example with two dates that is sure to please collectors. From the Pat Johnson Collection. Ex: Ernesto Sellschopp Collection (Swiss Bank Corp - 09/1988) Lot # 848 (part of)."
