In a paper published in the 1917 volume of this Journal, pp. 59 ff., I attempted to make available for the general student the results of some recent research on coins. The present paper is designed to continue the task thus begun. It follows the same plan and is subject to the same restrictions. General principles are stressed, while for details reference is made to the special publications noted on pp. 263, 264. Only the imperial issues, not the purely local or provincial, are considered.
