The article deals with six specimens of “irregular” deniers tournois and adds some considerations regarding their possible origin, stylistic conditions, classification and possible place in the history and numismatics of the late Frankokratia in Greece. All of the specimens are from the 14 th century and can be differentiated from the regular issues first by the base metal used for the planchets and second by the legends – they seem to be struck in copper rather than silver billon and the legends are mostly illiterate or pairing legends from two different issues. Although rather different in both style and fabric and perhaps manifesting some local characteristics, all of them seem to be copying the generic Clarentine denier tournois, the most long-serving and well represented coinage in 13th and 14th century Frankish Greece.
