[9] In 1597 he was appointed to a commission to set the value of foreign gold and silver money brought into the country, and in 1599 to one which studied how to reissue the circulating coinage.
[10] His last parliamentary act was in 1607, when he was appointed to a commission to assess a tax for the purpose of printing Regiam Majestatem, an edition of the old laws of Scotland.
In October 1579 at his Entry to Edinburgh, James VI was given a cupboard of silver gilt plate made by the Edinburgh goldsmiths Edward Hart, Thomas Annand, George Heriot, Adam Craig and William Cokky.
[13] Two letters from Heriot to Sir John Maxwell of Pollok survive, itemising work the goldsmith had in hand in around the year 1570, including a gold needle and needle case, a "hinger" with a picture, gold buttons, and tooth pick.
[20] On his eldest son George's marriage in 1586, Heriot gave him 1500 merks, in order that he could establish his own shop; he would go on to become jeweller and goldsmith to Queen Anne and King James VI, and amass a large fortune, which he bequeathed to establish Heriot's Hospital in Edinburgh.
[15] James succeeded as court jeweller after his brother's death,[26] and married Elizabeth Jossey or Joyce, the daughter of Robert Jousie, Keeper of the Robes, in January 1624/5.
