THESSALY, Thessalian League. Circa 150-100 BC. Stater (Silver, 22 mm, 5.49 g, 12 h), struck under the magistrates Dikaios and Onasimbrotos. Head of Zeus to right, wearing oak wreath. Rev. ΘEΣΣA/ΛΩN / ΔI-KAI[OC] / O-N/A/C-IM/B-P/P/OTOC Athena Itonia striding right, hurling spear with her right hand and extending shield in her left. BCD Thessaly II 880.1 ( same dies ). HGC 4, 210. Struck from fresh dies. Nearly extremely fine.

It is not certain whether the second P in the magistrate's name Onasimbrotos is part of the name, thus an engraver's error, or a monogram. If a monogram, it looks from this coin that it should be deconstructed to the Greek letters TP.
