Tostão 'V-L' – João III 1st Type, Lisboa mint

João III inherited a crown already stretched thin by the costs of maintaining Estado da India, and the tostão was the workhorse denomination that kept domestic commerce moving while specie drained east. The 'V-L' pairing in the mint mark reflects the partnership of the vedor and the monetary contractor responsible for that particular striking cycle — a bookkeeping convention of the Casa da Moeda that now serves as the primary tool for attributing emissions across Gomes references 98 through 101.

Silver fineness held at .9167 throughout João III's early coinage, though weight standards came under pressure as the reign progressed and the Crown's fiscal position deteriorated after the 1520s spice trade revenues began falling short of projections.
