Well it's not exactly new since i bought it a while ago, but;
Nicholas Mayhew, Sterling; The History of a Currency (London, 2000)
I've yet to read it despite the fact i've had it about 5 months. It is literally though a history of all the coinage acts and things right from the era Domesday Book (1080s) to the aftermath of the Second World War.
Includes such things as trade and mercantile activities, interest rates, exchange rates, import/export duties, financial matters and how they affected domestic and foreign policy. Some mention of the coinage itself, the first gold coinage of Henry III, the bullion shortages of the early 15th century, the shift to milled coinage. Bimetalism and the Gold Standard, fiat currencies. Decimalisation and the euro. No doubt mention will be made of the esterlings of the low countries and perhaps the Danegeld, although that is a little earlier than this book a few million silver pennies being paid to the Scandinavians regularly must get some mention somewhere. As will the coinage laws of Athelstan, one coin for the realm and the fierce punishments introduced for those found producing substandard coinage.
It should be an interesting read therefore.
