GREEK COINS
EGYPT

Period of Ptolemy VI and Ptolemy VIII, c. 180-116 BC. Tetradrachm (Gold, 24mm, 13.83 g 12), struck in the name of the deified Arsinoe II, but probably meant to represent Cleopatra II, queen of Egypt, c. 170-116, Paphos, regnal year ΛΒ = 32 = 149. Diademed and veiled head of Arsinoe II to right, wearing stephane and ram's horn and with a lotos-tipped scepter over her left shoulder. Rev. ΑΡΣΙΝΟΗΣ ΦΙΛΑΔΕΛΦΟΥ Double cornucopiae bound with fillet; in field to left, LΛΒ; in field to right, ΠΑ. Unpublished but cf. Svoronos 1446 (a tetradrachm of Ptolemy VI minted in Paphos with this date) and 1447 (a gold octodrachm from Paphos in the name of Arsinoe dated to year ΛΓ = 33). Of the greatest rarity, apparently unpublished and possibly unique. An attractive coin with a pleasant portrait. A few minor marks, otherwise, extremely fine.

From the Chrysos Collection, acquired in Geneva in 1980.
For a closely comparable and contemporary gold teradrachm in the name of Arsinoe (also from Cyprus, but minted in Salamis and dated to regnal year ΚΖ = 27 = 154 BC), see the until then unpublished piece from the Adda collection: Christie's 9 October 1984, 307. That coin was, somewhat astoundingly, ascribed to the mint of Alexandria (despite having the clear mintmark ΣΑ on the reverse!).
