I'm a fan of Mr. Ramskold and his research into the Constantinian period, so when he posted his article about the dynastic issues of Constantine I was very excited to read it. I am also a fan of the anepigraphic series so whenever a new auction appears, one of my interests is always regarding this series. These coins are rather regular for Constantine I and his sons Constantine II and Constantius, scarce for Crispus and rather rare for the Augustae Helena and Fausta. So here it appears this specimen, holed and corroded: AE17mm 2.38g follis Obv: Anepigraphic, diademed bust wearing imperial mantle and necklace. Rev: FL H / ELENA / AVGVSTA / SMANTB; Star in crescent above, dot below. Ref: RIC VII Antioch 61, rated R4. This is possibly the second issue of the "dynastic series" minted at Antioch perhaps in 325. The series started there and is to be put in the context of an imperial visit to the city in 324, when the first issue possibly began.
I have yet to read it, but will soon. Helena 318 to 319 AD Mint: Thessalonica AE Follis Obvs: HELENA N F, bare head right, waved hair, mantled. Revs: Laurel wreath enclosing eight pointed star. 17x18mm, 3.05g Ref: RIC VII.505.50, Vagi 2898
