1748/7 overdate - Acanthite collection

This date is one of a series struck 1747-57 for Ferdinand VI. It is distinguished from later issues (KM 67.2, 1757-60) of half reales by having similar crowns atop the pillars on the date side. The normal date is common, the 1748/7 overdate (shown below) is scarce.

Mexican numismatists hotly debate which side of the coin constitutes the obverse. Gilboy[1] 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.

Recorded mintage: unknown.

Specification: 1.69 grams, .917 fine silver, .049 troy oz ASW.

Catalog reference: Cayón-10158, Gilboy M-05-22 (normal date), M-05-22a (overdate), KM 67.1.
