Macuquina
Spanish: Cob coinage, the crude hammered and trimmed gold and silver coins of Spain and Spanish America produced from the 1500s until about 1732, when the screw press became commonly available. The name may come from Makkaikuna in the Quechua language of Cuzco, Peru and the nearby Inca empire, and is said to mean �the struck things.� In Spanish, �las golpeadas.� Others believe the word is from the Arabic mahcuc, for revising. These coins were not made by any manner of being �cut from a bar.�
