In citing units of currency, the old sterling denominations of pounds, shillings, and pence have been retained. There are twelve pence in a shilling (modern 5p or U.S. 8 cents), twenty shillings in a pound (£1 or U.S. $1.60), and so on. A mark is thirteen shillings and four pence (66p or U.S. $1.05). Rough estimates of modern values for sixteenth-century figures can be obtained by multiplying all the numbers by at least one thousand.
