The G mint mark next to the date on Akisu's 8 reales tells us it is from Guatemala. The legend HISPAN tells us it is from the Spanish colonies in the New World. These coins were minted with the pillars and Spanish royal crest design between 1754 and 1771.
The coins have different Spanish kings during different periods of time. For coins with this pattern, the kings of Spain were Philip (Phs), Ferdinand (Ferd, Ferdnd, Frdnd, Frd), and Charles (Carlos, Carolus, Carolvs, Carol, Car). Look for the name on the side with the shield and crown.
