This document discusses using linked open data and geographic analysis of ancient coin hoards. It provides examples of Roman coin mints located in Rome and hoards found in Oliver's Orchard near Colchester, England. SPARQL queries can be used to retrieve data about coins from a triplestore, including findspot locations and metadata. Geographic distributions of coin hoards can provide insights into archaeological contexts.
