peça [Portuguese]

A unit of value used in the trade in slaves passing from West Africa through the Cape Verde Islands to the New World, 16th – 18th centuries. Also called a boa peça, peça da India or, in Spanish, pieza de India (“piece of India”). One peça was the value of a male or female slave in good health between 15 and 25 years of age. Slaves between 8 and 15 years old, or 25 to 35, were valued at ²⁄₃ peça. Slaves younger or older than these groups, and those who were sick, were worth even less. The peça was used in assessing tariffs and establishing quotas.
