sterling: [13] Sterling ‘British money’ originated as a term for an English silver penny from the 13th to the 15th centuries. The first ones struck had the design of a small star on them – hence the name sterling (and its now defunct variant starling), literally ‘little star’. Two hundred and forty of such coins formed a unit of weight, known as a pound of sterlings. The earliest use of sterling as a general term for ‘English currency’ dates from the mid 16th century. => star[sterling etymology, sterling origin, 英语词源]
