Watch List notes:

SATRAPS OF CARIA. Maussolos, circa 377/6-353/2 BC. Stater (Silver, 25 mm, 14.54 g, 12 h), Halikarnassos. Laureate head of Apollo facing, turned slightly to right. Rev. ΜΑΥΣΣΩΛΛΟ Zeus Labraundos standing right, holding long scepter and double ax. Konuk, Identities 21. SNG Copenhagen 590. Toned and struck in high relief. Scratches and uncleaned deposits on the reverse, otherwise, nearly extremely fine/very fine.

From the collection of W. F. Stoecklin, Amriswil, Switzerland, acquired from Bank Leu in Zurich prior to 1975.

This coin is surely listed in K. Konuk's Oxford dissertation of 1998: unfortunately that dissertation has never been published.
