Mexico 1732-Mo 1/2 real
This 1732 1/2 real from the Mexico City mint is an example of the first design for pillar fractionals, where the obverse legend surrounds the periphery. In addition, this unique type does not display the denomination or assayers' initials on either side of the shield. Those elements were added later in 1732, and in 1742 the design was changed again, allowing the crown to extend to the rim. Gilboy lists this variety as extremely rare, with only a few pieces known to exist. The first specimen was lot 435 in Stacks Bowers Winter 2014 Baltimore sale, where it sold for $2,115. The catalog description noted, "MEXICO. 1/2 Real, 1732-Mo. Philip V (1700-46). NGC Good Details--Scratches. Without assayer's letter. VERY RARE first year of issue. Much nicer looking than the grade designated by NGC, some of the letters across the pillars are still visible. From the David Gray Collection. Ex: Ponterio & Associates Sale #130, Lot #656." The second specimen was lot 3121 in Stack's Bowers NYINC sale (New York, January 2017), where it sold for $4,700. The catalog description noted, "MEXICO. 1/2 Real, 1732. Philip V (17004). NGC VF-35. VERY RARE first year of issue for pillar coinage without assayer letter. Good Strike on a compact slightly oblong flan. Very pleasant with all elements present and none overly worn or erased. Surfaces toned to medium gray. A fantastic addition to any collection which is offered in decent problem free grades such as this all too rarely."
Mexican numismatists hotly debate which side of the coin constitutes the obverse. Gilboy depicts the shield side as the obverse as that side bears the king's name. However, auction catalogs and dealer listings more frequently use the pillars and globes side as the obverse, as that side bears the date.
