Stannary town

The word stannary is historically applied to:

The principal role of a stannary town was the collection of tin coinage, the proceeds of which were passed to the Duchy of Cornwall or the Crown. With the abolition of tin coinage in 1838 (following extensive petitioning by the Cornish tin industry for simplification of the taxation rules), the principal purpose for coinage town status ceased. However coinage towns still retained certain historic rights to appoint stannators to Cornwall's Stannary Parliament.

The English word ‘stannary’ is derived from the Middle English stannarie, through Medieval Latin stannaria (‘tin mine’), ultimately from Late Latin stannum (‘tin’) (cf. the symbol for the chemical element Sn). The native Cornish word is sten and tin-workings stenegi.

Devon stannaries are usually referred to by the names of stannary towns. These towns were the locations where refined tin (or white tin) was assessed, coined, and sold. They were also the location for some of the institutions associated with the operation of the stannary.

King Edward I's 1305 Stannary Charter established , Ashburton and Chagford as Devon's stannary towns, with a monopoly on all tin mining in Devon, a right to representation in the Stannary Parliament and a right to the jurisdiction of the Stannary Courts. Plympton became the fourth Devon stannary town in 1328 after a powerful lobby persuaded the Sheriff of Devon that it was nearer the sea and therefore had better access for merchants.
