Tasciovanos ruled the Catuvellauni from roughly the late first century BC, operating out of Verulamium — present-day St Albans — and his coinage marks one of the earliest sustained series of struck bronze from the British Iron Age. Most Celtic British bronze at this period was cast rather than struck, which makes the Tasciovanan struck series technically unusual for its time and place. The TAS abbreviation appearing on issues attributed to him is among the earliest examples of a ruler's abbreviated name used as a mint or issuing authority signature in pre-Roman Britain.
