Silver Chain with a ring and a trefoil attached by two small buckles. The chain has 41 links in the shape of the letter 'S'. This style of chain is known as a 'collar of SS' or 'of esses'. These collars were an emblem of John of Gaunt, Duke of Lancaster (1340-99), of his son Henry, who became King Henry IV in 1399, and of the other Lancastrian kings Henry V and Henry VI. Collars of varying degrees of value were presented to those the king wished to honour. A silver collar like this was probably made for someone below the rank of knight: an emblem of authority for a government official or an ambassador.
