DENARIUS
Roman silver coin equivalent to the Greek drachma; the daily wage of a laborer (Mt. 20:2, 9, 13).
The apostles estimated that at least 200 denarii of bread would be needed to feed the crowd of 5,000 men (Mark 6:37), which would have been equivalent to 1 denarius for every 25 people.
The prices of Rev. 6:6 show a period of hardship.
