A treatise on the coins of England and Ireland, and of foreign states, that are current in England, with coloured drawings of them. It was written after the year 1526, as appears from a reference to that year on f. 17, and contains a petition to the king to be allowed to coin in Ireland, and the other isles out of England, in gold and silver, and offers an annual payment of 8,000 francs for the permission. It also recommends a lowering of the standard.
