The aim of the WikiProject Numismatics is:

  • to define a set of properties that can be used to describe coins and banknotes in Wikidata:
  • to map and import all relevant data that currently is spread in Commons, Wikipedia, and Wikisource.
  • to establish methods to interact with this data from external projects, e.g., projects describing coin and banknote collections.

This entire page has to be updated following Wikidata:Project chat#Describing the two sides of a coin discussion.
