Watch List notes:

Square Ӕ Exagium Solidi Weight, designed from an Antoninus Pius Ӕ of Caesarea, Cappadocia. Struck circa AD 138–161, modified circa late 4th-5th centuries AD. [ΑΥΤ]ΟΚ Α[ΝΤѠΝЄΙΝΟС] СЄΒ[Α]СΤΟС, laureate head right / ΥΠ[ΑΤΟС Δ ΠΑΤΗΡ Π]ΑΤΡ, club. Cf. RPC Online 6719 var. (reverse legend). 4.45g, 17mm x 17mm.

Near Very Fine. A highly interesting choice of coin for a solidi weight and one which appears to have an unrecorded, abbreviated reverse legend.
