Can anyone help ID this coin? The tag says Ptolemy III from an "uncertain mint in Corinth". 20mm, 5.73 gms. I can not find corroborating photos or references.
Svoronos 1000.

Ah, ptolemybronze has finally loaded and here is their example: 20mm - 5.7gm Sv1000 (cornucopia at right) Additional info from PtolemyBronze: Ptolemy III - Royal Portrait Series 5 This denomination series consists of only 4 coins, all with very similar appearance but differing in size/weight. The familiar Zeus Ammon obverse is replaced with a portrait of Ptolemy III wearing the aegis and the reverse is the usual style of Ptolemy III wearing a closed-wing eagle and the cornucopia reignal symbol. These are found in the area of Corinth and likely minted locally for use by Ptolemaic settlements there at that time. The largest size (Svoronos 997) is about 17gm and not shown here. The middle size has two variants (Svoronos 998 and 999) which have the cornucopia on opposing sides of the eagle. Svoronos 998 and 999 (the two middle sized types with cornucopiaea on opposites sides) are shown here. The smallest size is about 6gm and also not shown here. The appearance of a contemporary Ptolemaic ruler's portrait on a bronze coin is unusual and may be unique to this series. These two are likely denominated as tritartemorion (six chalkoi) on the post-260BC weight standard. The largest size would seem to be a tri-hemiobol (ca. 17.2gm) and the smallest a hemiobol (ca 5.7gm). Edited to add: I see nothing that suggests is was struck outside of Alexandria, but you might want to read the various articles on PtolemyBronze's landing page.
