Amazon.com description: Product Description: Coins are one of the most abundant sources for our study of the past, yet their value as historical evidence is relatively neglected because of a general lack of knowledge of numismatic techniques. This volume of essays, offered by a circle of friends, colleagues and pupils working in Britain, Europe and North America, is intended to pay tribute to Philip Grierson's unique contribution to the study of numismatic method. A medievalist by training, through his wide-ranging interests in coins and coinage Grierson has commanded the respect of historians and numismatists of all periods for the originality and good sense of his prolific scholarship. More than any other living scholar, he has been responsible for making available an understanding of numismatic expertise to specialist and non-specialist audiences.
