Wikidata:WikiProject Numismatics

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/Archive/2017/10#Describing the two sides of a coin discussion.

You can edit these templates here: Wikidata:Cradle

Getting startedEdit

If you can't spend much time describing a new coin type, it may be a good idea to start with described by source (P1343) associated with a coin catalog (Q52666561), with appropiate qualifiers, including object stated as (P1932) so that other people can model the structured data, and subject named as (P1810).

Mentioning the content of hoards in terms of sets of coins (with type) and their cardinality is of significant interest. Hoard entities to be analyzed as potential templates:

Individual coinsEdit

There are several instances of coins in Wikidata. Some are really instances and not sub-classes, e.g., those of the Museum of Toulouse:

You can find them (and a lot of mistakenly classified coin types) using the following query

#Individual coins (instances)
SELECT ?item ?itemLabel ?itemAltLabel ?itemDescription
WHERE 
{
  ?item wdt:P279*/wdt:P31 wd:Q41207.
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en,it,fr,es,de,ru,hu". }
}
Try it!

And you can find coin types (classes and sub-classes) using the following query

#sub-classes of the coin class
SELECT ?item ?itemLabel ?itemAltLabel ?itemDescription
WHERE 
{
  ?item wdt:P279/wdt:P279* wd:Q41207.
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en,it,fr,es,de,ru,hu". }
