–To make five sorts of money of Crown Gold,
One Piece which shall be called the quarter Guinea or five shillings & three pence piece running for five shillings & three pence sterling, & there shall be one hundred seventy & light of these in the pound weight Troy.
One other piece which shall be called the half Guinea or ten shillings & six pence piece running for ten shillings & six pence sterling & there shall be eighty & nine of these in the pound weight Troy.
– excepting only the Quarter Guineas. For because these pieces cannot be sized with the same exactnesses as the larger pieces of gold moneys may be, there shall be added to the Remedy in weight, one half grain for every four quarter Guineas in the pound weight Troy of the moneys tried. So always that the same default happen by Casualty, Otherwise not.
