Callet was a small Turdetanian settlement in the Baetis valley — modern Andalusia — whose coinage reflects the patchwork of semi-autonomous minting that Roman provincial administration tolerated, and sometimes encouraged, across Hispania Ulterior during the second and first centuries BC. The town's bronze issues are among the more obscure in the Hispano-Roman series, with ACIP 2411 representing essentially the full extent of what survives attributed to this mint.

The Turdetanians were noted by Strabo as the most culturally Romanized of the Iberian peoples well before formal municipalization.
