Nice siliqua by Julian II, called the Apostate in Christian sources, because being baptized and coming from a Christian family, he returned to the pagan religion. Siliqua was the basic silver denomination in the 4th century, they are definitely rarer than bronze denominations, and they were also quickly devalued by lowering their weight, while maintaining the high quality of silver.
