Can Linked Open Data capture the changes in value through changes in the weight of a Roman denomination, and identify them with historically documented events? With Linked Open Data, large amounts of information can be generated without affecting the quality of the data. Consequently, can Linked Open Data and the quantitative approach be used to make scientific statements? A SPARQL query is used for data acquisition to generate a list of all coins of a given denomination. All coins of the queried denomination from collections linked to OCRE are included in statistical analyses. Using this data basis we can show that the quantitative approach can generate good results even when the database is not controllable. Thus, we can demonstrate that historical events definitely coincide with changes in the weight of coinage.
