Vintém 'ºM - ºL' - Manuel I Lisboa mint

The vintém was introduced under Manuel I as part of a sweeping monetary reform that rationalized Portugal's silver coinage ahead of the commercial explosion brought on by the India route. Minting at Lisboa ran continuously across Manuel's entire reign, and the ºM - ºL privy mark pairing — mintmaster alongside mint — reflects the administrative layering Portugal imposed on its mints as transaction volumes from Atlantic and Indian Ocean trade surged beyond anything previous coinage structures had been designed to handle.

Gomes E1 28 is among the more frequently encountered vintém attributions for this reign, but die alignment irregularities are common across the type.
