instead of leaving England’s money with two different possible values—the “intrinsic” market price of its metal and its “extrinsic” denomination as some number of shillings and pence—those separate measures must be brought into agreement. To make this happen, Newton proposed raising the face value of the coinage by about one-quarter, so that, for example, the crown, a five-shilling piece in the old system, would now be worth six shillings three pence.
