American Journal of Numismatics [First Series], American Numismatic Society

The American Journal of Numismatics (Series One), published from 1866 to 1924 by the American Numismatic Society (originally the American Numismatic and Archaeological Society), acted as the standard bearer of American numismatics for many years.  Although later issues are dominated by foreign and ancient content, the early and middle part of the run features American information found nowhere else.  

Note: Sets of the American Journal of Numismatics were often assembled with several years bound in one volume.  If you don't see the year you are looking for, check the closest preceding year.
