'Denarii' in the Bible

"But when that servant went away, he found one of his fellow servants who owed him a hundred denarii. He grabbed him, seized him by the throat, and said, "Pay what you owe!'

But he answered them, "You give them something to eat." They asked him, "Should we go and buy 200 denarii worth of bread and give it to them to eat?"

This perfume could have been sold for more than 300 denarii and the money given to the destitute." So they got extremely angry with her.

"Two men were in debt to a moneylender. One owed him 500 denarii, and the other 50.

The next day, he took out two denarii and gave them to the innkeeper, saying, "Take good care of him. If you spend more than that, I'll repay you when I come back.'

Philip answered him, "Two hundred denarii worth of bread isn't enough for each of them to have a little."

"Why wasn't this perfume sold for 300 denarii and the money given to the destitute?"
