There doesn't seem to be much info on these coins on CT, so I am starting this thread to share resources and examples of these coins. This article a nice place to start: https://coinweek.com/ancient-coins/coinweek-ancient-coin-series-ancient-coinage-of-yemen/ The alphabet picture at the link above useful for decoding the lettering: AR Quinarius South Arabia, Himyar Ruler: Amdān Bayān Yuhaqbiḍ Date: Circa AD 100-120. Mint: RYDN Obv: Head within circular torque; monogram to left Rev: Head right; MDN BYN ‘scepter’ to right, mint signature RYDN in exergue. Size: 12.3mm and 1.41g Ref: Munro-Hay 3.4i This 2010 Article Coinage of the Caravan Kingdoms edited by Martin Huth and Peter G. van Alfen was my second stop. In which Christian Robin describes six Ḥimyarite rulers that appear on coins. Mubāhil dhu-Raydān (Mbhl ḏ-Rydn) (before 30 BCE) Shammar dhu-Raydān (c. 30 BCE) Karibʾīl Watār Yuhanʿim (c. 40–70 CE) Amdān Bayān Yahaqbiḍ (c. 100–120 CE) Dhamarʿalī Yuhabirr (c. 135–175 CE) Thaʾrān Yaʿūb Yuhanʿim (c. 175–215 CE) The coin above is a coin of ʿAmdān Bayān Yuhaqbiḍ who struck coins in the name of either ʿAmdān Yuhaqbiḍ or ʿAmdān Bayān (ʿmdn Byn). Although attributions describes RYDN as the mint - this note from Christian Robin's article: "On Ḥimyarite coins, the term ‘Raydān’ (Rydn), invariably placed in the exergue, denotes the Royal palace at Ẓafār. There is little probability that these Royal palaces housed the respective mints of these kingdoms: contrary to the usual practice, Raydān, Ḥarīb, and Shaqir should thus not be interpreted as mint-names." Three other resources: - 2011 Coinage of the Caravan Kingdoms by Martin Huth, is referenced in the article above - 1991: The coinage of Shabwa (Hadhramawt), and other ancient south arabian coinage in the national museum, Aden S.c.h. Munro-Hay - 2003: Coinage of Arabia Felix: The Pre-Islamic Coinage of the Yemen by Stuart Munro-Hay Images of coins of the Himyarite Kingdom, other references to resources or corrections to the information above are appreciated.
