Within a beaded border, the reverse features, from left to right, the female representations of Ireland, England and Scotland. They are identified by the implements at their feet - respectively a harp, a shield bearing the cross of St George and an oversized thistle; additionally, the also carry floral symbols in their crowns: shamrocks, roses and more thistles.
The engravers name W. WYON. is to the left of the harp.
England, (or maybe Britannia), is perhaps the elder sister, standing taller than the other women who look at her with affection. This is an idealised representation of the union between the three nations, formed as the United Kingdom of Great Britain and Ireland in 1801. Wales is not represented here, but then that would have disrupted the neat parallel with the three charities of Greek mythology.
The design owes much to Antonio Canova's famous statue, The Three Graces - hence the coin's nickname; however, the figures in the statue are naked while those on the coin are fully dressed, in Classical style.
The inscription around above, interrupted by the figures, reads FOEDUS INVIOLABILE (Inviolable League).
In the exergue, a crossed palm frond and a ship's rudder. The palm frond symbolises both victory - reminding of the recent victory at Waterloo - and peace. The ship's rudder is a symbol of the British maritime might.
