A Roman coin or denomination of money, in value the fourth part of a denarius, and originally containing two asses and a half, afterward four asses, -- equal to about two pence sterling, or four cents.

☞ The sestertium was equivalent to one thousand sesterces, equal to £8 17s 1d. sterling, or about $43 (in 1900), before the reign of Augustus.
