Notes: The attribution of this rare issue has been the subject of much debate. While the types mimic issues in the name of Olynthos (cf. SNG ANS 466), some scholars believe that the legend on this piece is only logical for an issue from Chalkis in Euboia, since there is no evidence for a Chalkidian League prior to 432 BC, a date certainly too late for this issue. W. Greenwell, who first published the issue in NC 1897, though, suggested that this coinage may be the sole evidence extant of an earlier league, noting the close similarity of the Olynthos-named issue, and the unlikeliness of it being an issue that fit into the scheme of coinage at Chalkis. H. Gaebler, in AMNG, dismissed Greenwell’s theory and said the issue was certainly from Chalkis, noting also that the eagle is flying right as a Chalkis, rather than upward as on the issues of Olynthos. On close examination, though, this stylistic distinction is almost certainly incorrect. Robinson & Clement noted the weakness of Gaebler’s arguments, and placed the issue at Olynthos, based on the similarity to the Olynthos-signed tetrobols, but also admitted that “the series is still an enigma.” Greenwell’s argument still seems to be the most persuasive, especially given that our knowledge of the corpus of coinage at Chalkis is much better today; this issue simply does not seem to have a place at that city, and other than the “enigmatic” legend, there is no compelling reason to assign it elsewhere. This issue was most recently discussed by S. Psoma, who places the issue at Olynthos in the mid-5th century, and notes that the legend references “the Chalkidians of Olynthos” (cf. S. Psoma, Olynthe et les Chalcidiens de Thrace [Stuttgart, 2001], Appendix, pp. 253–61).
