【4周达】杰克逊的印记：从 1300 年至今的英国、苏格兰、爱尔兰银金标记 Pocket Edition Jackson's Hallmarks of English, Scottish, Iris~

During the last twenty-three years important developments have taken place in the Hallmarking system. Most notably the introduction within Europe of a universally accepted system of marking has led not only to the addition of new marks, but als, to a change of status of several historic marks.

This edition brings to present day all the date letters and commemorative marks. It also includes the recently introduced marks for Palladium and a section illustrating the Assay Office identification marks of those countries that are signatories to the International Convention marking system.

In addition and of importance are the changes made in the early cycles of Dublin date letters which result from recent research by silver scholars in Ireland.
