Survival of stannary records has been rather patchy. The Cornwall Record Office has records from the Vicewarden's Court of the Stannaries of Devon and Cornwall, mostly from the mid nineteenth century onwards, which is rather late in the overall history of the stannary organisations. Earlier survivals in the CRO include the Tin Abstract Books from the Truro Tin office for 1703–10 and 1833–35. These books record the quantities of tin coined in the various coinage towns of Devon and Cornwall, the purchase of tin by the crown and the shipment of this tin by sea to London.
