Salpesa was a small Iberian town in the Baética region whose exact location remains debated among scholars — most place it near modern Écija in Andalusia. Its bronze coinage was produced under Roman provincial authorization during the late Republican period, when Rome permitted Hispanian communities to strike local bronze for regional circulation while maintaining tight control over silver.

The ACIP 2317 attribution reflects work from the landmark 2006 corpus by Ripollès and Abascal, which significantly revised earlier CNH classifications for Baetican issues.
