Notes "Introduced as part of the currency reform of 211 BC, the silver quinarius was initially tariffed at one half of a denarius and five copper asses. Along with the silver sestertius, it ceased to be regularly minted after about 208 BC and was struck only sporadically thereafter. The periodic strikings that did occur were intended to facilitate trade with the Celtic tribes in Gaul and Britain, who seemed to appreciate the coin's small size and even struck their own imitations of Roman quinarii. The issue of L. Piso Frugi in 90 BC complemented that moneyer's enormous output of denarii, which helped finance the Social war raging in Italy."
