Siliqua is the modern name given (without any ancient evidence) to small, thin, Roman silver coins produced in the 4th century A.D. and later.
Correspondingly, the half-siliqua is a coin weighing half of what the siliqua weighed.
When the coins were in circulation, the Latin word siliqua was a unit of weight defined as one twenty-fourth of the weight of a Roman solidus.
