| 裏面の説明 | A passant lion facing left stands upon a raised ground line in the centre of the field, with a tall palm tree rising prominently behind it. Two imperial crowns are placed flanking the lion in the lower field, one to the left and one to the right. The legend EAST INDIA CO. arches across the upper portion of the field. In the exergue, the inscription ANNO DOMINI above the date 1830 is incused on a raised tablet. The entire design is enclosed within a dentillated border, and the composition reflects the heraldic idiom used on East India Company coinage of the period. |

The William IV mohur was struck at the Calcutta Mint beginning in 1830, the same year William IV ascended the throne following the death of George IV. The East India Company had been issuing gold mohurs under British royal authority since the late eighteenth century, but this series coincided with a period of intense parliamentary scrutiny — the Company's charter was due for renewal in 1833, and the renewal ultimately stripped it of its remaining trade monopolies entirely.
Calcutta mohurs of this type are notorious for uneven surface quality due to the mint's reliance on locally drawn gold of inconsistent fineness, which required periodic assay adjustments mid-production.
