The enigmatic 'O / C S / C' star medalettes were described by Ramskold, Coins and medallions (2011) and attributed to Constantinopolis, but in light of recent discoveries, an attribution to Thessalonica must now be considered. No convincing interpretation of the letters 'O / C S / C' has yet been found.
