Joseph J. Mickley, first president of the NAS.

The Numismatic Society of Philadelphia was established on January 1, 1858 by a group of eight numismatists, including Joseph J. Mickley and William Sansom Vaux, becoming the first numismatic society in the United States. Mickley became the society's first president but eventually resigned. On March 23, 1865, the name was officially changed to the "Numismatic and Antiquarian Society of Philadelphia", due to the belief that the sole study of numismatics was not enough to keep the society in a prosperous condition. Prior to 1883, a constitution was approved for the society, and eventually a common seal was introduced. Subsequently, the society was also able to hire a hall as a place of meeting.


The society consists of a president, two vice-presidents, a recording secretary, a corresponding secretary, a treasurer, a historiographer, at least one curator, and a librarian. The Director of the United States Mint is ex officio an honorary member of the Numismatic and Antiquarian Society of Philadelphia.

New members must be proposed by two members at a meeting, and then voted for by the society, and each member must pay a fee to the treasurer for being part of the society.
