How much is 100 Denarii worth?

In Luke 10:35 the good samaritan paid the inn keeper with two denarii.

A denarius (Greek) was a small silver being the equivalent of a full day's wage. The Bible refers to the denarius as a day's wage for a common laborer (Matthew 20:2).

Classical historians regularly say that in the late Roman Republic and early Roman Empire the daily wage for an unskilled laborer and common soldier was 1 denarius without tax, or about US$20 in bread. By this estimate 100 denarii is about $2000 USD in modern times.
