The Broad was an English coin worth 20 shillings (20/-) issued by the Commonwealth of England in 1656. It was a milled gold coin weighing 9.0–9.1 grams, with a diameter of 29 or 30 millimetres, designed by Thomas Simon (also called Symonds). The current value of the coin in "very fine" to "extremely fine" condition is £3,500 to £6,000 as the pieces are very rare, but normally fairly unworn, although a Mr Pinkerton, writing at the time that the coins circulated, noted that many of the coins in circulation were so worn as to be almost flat.
