Most popes were incredibly rich in office. Until recent times that was one of the attractions of being a pope. However, almost nothing is known about Clement I apart from some Church traditions, none of which would reveal his wealth.
Francis A. Sullivan SJ (From Apostles to Bishops) says that if Clement existed he was probably no more than a presbyter in Rome, since most scholars are of the opinion that the church of Rome would have been led at that time by a group of presbyters, and that bishops were not appointed to the church in Rome until later in the second century.
