<p>The studies assembled in this volume are dedicated to the memory of Albert Baldein, a professional numismatist whose chief interest lay in helping other numismatists, professionals, students and collectors alike, some of whom record their appreciations here. The contributions, though they are drawn from a wide variety of fields - Greek, Roman, Dark Age, Byzantine, English, Scottish, Irish and European medieval coins, and medals - are all concerned with one or more facets of the theme set out in the title. Within the general concept, the essays deal with a diversity of subjects: </p><p>* identification of mints <br>* attribution of coins to specific mints<br>* coinage current in particular periods<br>* composition of groups of coins in a given series<br>* establishment of the correct sequence of issues of such groups. </p><p>The essays also demonstrate the use of particular numismatic techniques such as die-linking, the analysis of hoards and their statistics, the minute observation of changes in titulature and inscriptions and comparison of portrait styles. There is much new, exciting and well-illustrated material for numismatists, and chapters such as those on Scottish mints and Hadrian's COS III coins will be of interest to historians.</p> <p>1.
