This specimen was lot 71682 in Stack's Bowers Collectors Choice sale (Costa Mesa, CA, November 2022), where it sold for $336. The catalog description[1] noted, "MEXICO. Cob 4 Reales, 1732-Mo. Mexico City Mint, Assayer Felipe Rivas de Angulo (F). Philip V. PCGS Genuine--Filed Rims, EF Details. This argent 4 Reales piece displays a bold date, mintmark, and assayer. The portions of the shield and cross that fit onto the compact flan are pleasantly detailed. This piece does exhibit some edge filing that accounts for the Details designation and slightly lower weight. A piece with abundant overall eye appeal. 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.
