Two double-sided circular red wax seal impressions of the Great Seal Deputed for the Province of South Carolina during the reign of George III. Each within a circular ebonised wooden frame.

The obverse shows the royal arms for George III with supporters; the reverse shows George III robed and standing before a kneeling, bare-breasted woman who reaches her hand out towards him. The motto beneath reads Propius Red Adspice Nostras, a quotation from Vergil's Aeneid which may be translated 'Look more closely upon our affairs'. Around the scene is the inscription Sigillum Plagae Australis Provinciae Nostrae Carolinae ('The Seal of the Southern Part of our Province of Carolina').

Great Seals Deputed were used in British colonies to authenticate local laws, grants of land and writs in the king's name. Double-sided silver seal matrixes, like those for New York, Virginia and Georgia, would be pressed through paper onto each side of a single disc of wax. The resulting impression was affixed to the bottom of the legal document by ribbon or a parchment strip.

This seal was designed by His Majesty's Engraver of Seals, Christopher Seaton, in 1767. The composition follows seals produced as early as 1690, for the colony of New York: a standing British ruler is attended by a kneeling subject dressed conspicuously in local costume and holding resources which hint at the untapped wealth of the colonies. Depicting indigenous populations semi-clothed was visual trope used to justify non-European populations' need for 'civilisation'.

This seal is similar in design to the first Georgian seal produced for South Carolina, during the reign of George I, in 1721, and to that produced for the reign of George II in 1729. However, the monarch no longer holds an orb in his hand, and bends more graciously towards his subject in a lighter, more sensitive rendering.

The silver seal was dispatched by ship with others newly prepared for the North American and West Indian colonies in the spring of 1767, and likely arrived in the Americas that summer. The matrix for the South Carolina Great Seal Deputed is the only one for the North American colonies of George III's reign to survive today, in the British Museum.
