BRUTTIUM, Rhegion. Circa 415/410-387 BC. Æ Hemiobol (6.61 gm).
  RHGINON, laureate head of Apollo right, hair gathered into a roll and
  tucked into laurel wreath / H within linear circle; laurel wreath
  around. Larizza, "Rhegium Chalcidense," Rome 1905, 40 (same obverse
  die); SNG ANS -; SNG Copenhagen -; Garrucci pl. 114, 33; Virzi -; SNG
  Morcom -; Laffaille -. EF, dark green, almost black, patina, minor
  roughness. Only a handful known of which this is probably the finest.
  Extremely rare. ($2000) Struck as an alternative to the rare silver
  hemiobols, also marked with denominational value H, this coin is in
  the refined style of the lion's mask/Apollo head tetradrachms (ANS
  657-663) by the maestro della foglia which replaced the fully
  classical and severe Iokastes series (ANS 635-642), This issue no
  doubt owes its extreme scarcity to its having been struck on a heavy
  weight standard that failed to correspond to the trend, both in Italy
  and Sicily, towards lighter weights and a more fiduciary character of
  bronze coinages.

Triton V Sale, 15 Jan 2002, lot 97.
