30 Réis - Maria I Dio mint

正面描述	Central field bearing the Portuguese royal coat of arms, executed in low relief in the hammered style typical of late 18th-century colonial coinage. The shield, though heavily worn and encrusted, displays the characteristic quartered composition of the arms of Portugal under Queen Maria I. The surrounding field is largely plain, consistent with the crude fabric of Goan copper issues of this period. The denomination numeral '30' appears as part of the design. The overall strike is irregular, reflecting the primitive hammering technique employed at the Dio (Diu) mint.

背面描述	Central field displaying a bold cruciform design formed by interlocking rounded lobes or pellets arranged in a cross pattern, a decorative motif characteristic of Portuguese Indian copper coinage of the Maria I period. The cross-like arrangement of circular elements occupies the majority of the flan, rendered in relatively high relief compared to the obverse. The flan edges are irregular and slightly flan-cracked, consistent with the hammered manufacture at the Diu mint. The field surrounding the central device is largely unadorned. No legend or inscription is present on the reverse.
