I can't see clearly the regnal year, which is usual for Constans II
coins, even if this one is struck on a larger flan
than others. A Constans II follis
in a 638 conquered teritory is not a very big issue, for he starts his
reign in 641. Local greek communities still
existed at this time and probably used their own coins. Also the arab state was at its very beginning, without chrystalized structures, which explains the presence of arab-byzantine
imitations. The trade is out of the question as an explanation in our case, because long distance trade was not made with bronze coins.
