Publius Crepusius must have the rare distinction of being essentially unknown outside the coins he issued as moneyer, yet having a significant amount of research dedicated to these coins. What we know of him and his family is practically limited to a single short statement: he was one third of the triumvir monetalis in 82-81 BC. So little is known about P. Crepusius that Michael Crawford, author of perhaps the most important reference book on Roman Republican coinage, had only this to say of him: “The moneyer is a P. Crepusius, not otherwise known”
