Illyria, Dyrrachium. AR Drachm. 200-30 BC according to SNGCop.

obv: MENISKOS, cow & calf, Nike flying above with wreath, thunderbolt in ex 
rev: DYR KAL LW NOS around double stellate pattern.

From Dr. Gyula Petranyi, an expert on the coins of Dyrrhachium and 
Apollonia,  (see link to his website at the bottom of the WildWinds Dyrrhachuim pages),

"The Meniskos-Kallonos issue was most probably the 5th emission calculating
backwards from the end of minting of this series in Dyrrhachium, based on my
comparative hoard analyses, style and weight characteristics. In addition to
the reference numbers, it is also BMC 81-3. A rather common issue but Nike
rarely strikes up, she is quite well visible on your piece, flying over the
name and with wreath in hand. The coin shows signs of hasty production,
characteristic for this latest phase. Hardly available in better condition.
The exact date, however, is rather uncertain. Somewhere around the 70's of
the first c BC."
