Tin–Lead Sewn Tokens From 13th‐Century Gdańsk: Assessing Local and Non‐Local Production Through Archaeometric Analysis

ABSTRACT This study presents the results of an interdisciplinary investigation of 98 tin–lead sewn tokens from 13th‐century Gdańsk, the largest assemblage of its kind in Central Europe. Combining archaeological context, typology, SEM‐EDS and lead isotope analysis, the research explores provenance, production and function. Seven iconographic types were identified. Alloy compositions vary by type, indicating variation by type, reflecting batch‐related trends and routine variability. Lead isotope ratio data (MC‐ICP‐MS) indicate British lead sources; import of finished tokens is more likely, though local casting from imported lead cannot be excluded. The tokens' spatial concentration and diversity suggest integration into local economic practices. Their function remains uncertain, but tokens were integrated into Gdańsk's early urban economy.
