| Additional information |
The vintém was a 20-réis piece, and under João III its production at Lisbon became entangled with the administrative pressures of maintaining Portugal's sprawling Atlantic and Indian Ocean trade networks — coinage quality suffered as the mint prioritized volume. The isolated "Y" designation distinguishes a specific die arrangement within this emission, documented across three Gomes varieties that differ in subtle legend punctuation and cross terminal details rather than any fundamental design revision.
João III's reign saw chronic underfunding of domestic mint operations relative to the bullion flowing through Lisbon from Brazil and the Estado da India — most of that silver moved outward, not into domestic coinage.
