Vintém - João II '•L• - º' at each side of 'Y', Lisboa mint

João II inherited a monetary system badly strained by the costs of African fortification and early Atlantic exploration. The vintém, worth 20 réis, was among the workhorse denominations of his reign — struck in quantity to meet the demands of a cash economy expanding faster than the Crown's ability to control it. The Lisboa mint was the dominant production center, though output records from this period are fragmentary at best.

The Gomes reference J2 13 distinguishes this piece by the specific punctuation flanking the 'Y' — a detail that mattered to contemporary die-cutters working within a system of overlapping types where small marks served as internal mint controls.
