That amount, in British coin, is some 20,000 pounds sterling, which represents two days’ produce for the Mint at the Tower; so Lothar’s factor will have to deliver some three tons of bullion to the Tower mint no later than the 17th of June. This will present something of a challenge even to a man of Lothar’s resources, and so he has been careful to insert a proviso on the four 45-day bills stating that they must be presented to the House of the Golden Mercury, Change Alley, London, no later than fifteen days before the date of expiry, i.e., the stroke of midnight, 5 June.
