Watch List notes:

KINGS of MACEDON. temp. Alexander III – Antigonos I Monophthalmos. Circa 333-305 BC. Æ Unit (19mm, 8.34 g, 5h). In the name of Alexander III. Uncertain mint in the Troad (Alexandreia Troas?). Head of Herakles right, wearing lion skin / Charioteer, holding kentron and reins, driving fast biga right; trident head below. Price 1587; Bellinger A1; Meadows, Earliest, p. 49 and pl. 3, 1. Dark green-brown patina, traces of earthen encrustation, minor roughness, light cleaning scratches. Near VF. Extremely rare, only six published: 3 in excavations at Troas, one each in the BM and BN, and Bellinger noted an example in Imhoof-Blumer's collection (current disposition is unknown, but illustrated in AMNG III/2, pl. XXXI, 26); there are none in Pella, and only one in CoinArchives (CNG 114, lot 125).

Bellinger attributed this issue to Troas based on the presence of the three coins found in the excavations at Troy. Price thought the issue was from the Troad, but deferred to Bellinger on it's placement at Alexandreia. Meadows doubts the attribution to Alexandria, but agrees with Price that it likely is from the Troad.
