The original American Journal of Numismatics was established in 1866 as a monthly newsletter for the Society. Over time it came to include more substantial numismatic articles, but it was discontinued in 1924. In 1989, the name was revived for what had previously been called the American Numismatic Society Museum Notes. This second series of the American Journal of Numismatics is one of the world's leading scholarly journals in numismatics. It is published as a single hardcover volume annually, containing article-length works of original research in all areas of numismatics. The Numismatic Notes and Monographs series, established in 1920, is generally for shorter book-length works on relatively specific topics. It is published in 6" x 9" hardcover format.
