Guatemala 1770-G 1/2 real
Shown is a 1770 half real from the Guatemala mint, of a type issued 1754-1771. 1733 was the first year the Guatemala mint struck coinage, having first applied for authorization from the Spanish crown in 1714. The machinery was brought from Mexico City, and had already seen much service. As a consequence of that, and the fact that in Guatemala there were few people skilled in striking coins, production of milled coins equivalent to those being produced at Mexico City was not economically feasible. In 1754 the machinery and level of skill permitted issuance of round, milled coins, though local fabrication of dies was not at the same technical level as the Mexico City mint.
The example shown was sold on April 29, 2010 at an auction by Aureo y Calico for 105 euros.
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.
