denarius = "containing ten"
1) A Roman silver coin in NT time. It took its name from it being equal to ten "asses", a number after 217 B.C. increased to sixteen (about 3.898 grams or .1375 oz.). It was the principal silver coin of the Roman empire. From the parable of the labourers in the vineyard, it would seem that a denarius was then the ordinary pay for a day's wages. (Mat 20:2-13)
