| 正面描述 | Crowned Portuguese royal arms displayed at center, featuring the quartered escutcheon with castles and shields, set within a beaded or plain inner circle. The overall design is characteristic of the late 17th-century Portuguese minting style under King Pedro II. The field shows the heraldic devices rendered in low relief, consistent with a pattern or trial piece of the period. The coin bears visible surface wear and patination consistent with its age. |

The date range here is suspicious — a "vintém" denomination in this form, at this weight, attributed to the Porto mint in the late 17th to early 18th century, almost certainly places this within the broader monetary reforms Pedro II pursued to regularize Portuguese coinage after decades of debasement and wartime fiscal strain. The Gomes pattern classification signals this never entered circulation; it was a proposal, not a production issue.
Porto's mint activity during Pedro II's reign was intermittent and heavily subordinate to Lisbon.
