text_A: Cities in the Roman Empire often continued to issue their own coinage. "Of the many themes that were used on local coinage, celestial and astral symbols often appeared, mostly stars or crescent moons." The wide variety of these issues, and the varying explanations for the significance of the star and crescent on Roman coinage precludes their discussion here. It is, however, apparent that by the time of the Romans, coins featuring a star or crescent in some combination were incredibly rare.
text_B: Would you be likely to find a coin with a single star but no crescent on it at a Roman Empire archaeological site?
NO.
