Mexico City Mint, Assayer Francisco de la Pena (F) and Manuel de la Pena (M). Philip V. PCGS Genuine--Holed, EF Details. A stunning example of this RARE and sought-after Klippe issue. The coin displays a well-centered and bold crowned shield flanked by assayers' initials, mintmark, and denomination, all of which are presented with great clarity. On the rim, the full date is fully readable and only slightly cut off. The intricate reverse cross is no less well-struck, positioned in the center of the planchet and complete. A portion of the legend reading 'HISPANIA' is clear on the right. The surfaces are quite original, showing elegant dove gray toning. A hole is present on the lower rim, as is common for the issue. This wonderful example is sure to inspire competitive bidding on account of its elusiveness and wholesome condition. From the Pat Johnson Collection." The Latin American mints were ordered to cease production of cobs in the 1720's. Mexico City, being the largest mint, was the first to convert to milled coinage, starting in 1732. Not only were screw presses installed to strike the coins, but screw presses were needed to cut the blanks and edging machines were required to apply the floral edges. While European mints had been producing coins by this process for decades or even centuries, the Mexico City mint struggled with the transition. Cobs were also made in 1732 and "klippe" style four and eight reales were made 1733-34 as the mint attempted to change its methods and keep up with production. Similar milled coinage was not introduced to Lima and Guatemala until the 1750's and Potosi stalled until 1769.
