Sisipo was a small Iberian mint whose precise location remains unidentified — one of several indigenous Hispanic communities that briefly struck bronze coinage during the Roman Republican period, likely under some degree of Roman administrative pressure to produce local fractional currency. The ACIP and CNH references place this among the earliest documented issues from the site, suggesting the mint had a short operational life.

Almost nothing is known about Sisipo's civic history beyond what its coins imply.
