Mossman and Cockie helped Kirkcaldy pledge the queen's jewels, which had been stored in the castle, for loans.Bruce Lenman, 'Jacobean Goldsmith-Jewellers as Credit-Creators: The Cases of James Mossman, James Cockie and George Heriot', Scottish Historical Review, 74:198 (1995), pp. 159-177. Cockie, as archival evidence shows, was particularly involved in receiving silver and minting coins in the castle. The coins minted in the castle were finer than those minted at Dalkeith by the opposition.Michael Lynch, Edinburgh and the Reformation (Edinburgh, 1981), p. 145. The types included the eighty pence piece or half merk, known as a "six and eight." In June 1572 the English soldier and Marshall of Berwick William Drury sent one of Cockie's half merks to William Cecil as a novelty.Harry Potter, Edinburgh Under Siege: 1571-1573 (Stroud, 2003), p. 97: Calendar State Papers Scotland, vol. 4 (Edinburgh, 1905), p. 339.
