EΠIIn ancient Greek, EΠI is is a very common preposition and adverb that
means above, towards, near, about, etc. On coins it precedes the name of
the magistrate(s) and means "in  the time of" or "under the authority
of."

ΕΠΙ can also abbreviate the title epimeletai a Greek title (επιμεληται) used
for various officials and functionaries, who ‘take care of something’
(epimeleîsthai). The author of the Aristotelian Athenaion Politeia
mentions for Athens the epimeletai of wells (43,1), of the market
(51,4), of the festival of Dionysia (56,4), and of the Eleusinian
Mysteries (57,1). Also documented are epimeletai as court officials who
deal with the tributes in the Delian-Athenian League (ML 68), epimeletai
of shipyards (such as IG II2 1629, 178-179; Dem. Or. 22,63. Epimeletai
was sometimes the title of a supervisor, a Royal deputy for a polis or a
governor. Antipater I the Idumaean, the father of Herodes the Great,
was called 'epimeletes of the Jews'. In Roman times, when epimeletai
appear on coins, the title usually refers to magistrates who were in
charge of the coinage of the polis.Unfortunately, when epimeletai
is abbreviated, it can be difficult to
differentiate between EΠI in the sense of 'struck under' or 'struck in
the time of' and EΠI as an abbreviation of the title epimeletes. In
Grimenothyrae, f.i., most coin legends naming Loukios Tullios Per. start with the short EΠI, and it is only through a few types with the longer EΠIM that Loukios' title epimeletes becomes apparent (RPC III 2481ff.).
