La Fiel Executoría of Mexico City — posted prices, sealed weights, and the indigenous sellers exempted from both

The market magistracy of Mexico City: the corregidor and the regidores fieles executores, on a perpetual grant from Charles V and Juana, under ordinances of 1718 confirmed in 1724. By the viceregal ordinance of 1619 they posted fruit prices weekly and grocery prices monthly on a board in the plaza, priced bread alike for bakers and shopkeepers, and allowed the seller a profit "moderada" for his work and risk — while leaving indigenous vendors outside the price regime altogether.
