I am very confused, trying to understand the Sages' view on the monetary system of the Torah, and the commentaries do not present a holistic and consistent view.
I am also confused by the historical evidences that the monetary system (based on money units, not barter, i.e. טבעא, not פירא) is relatively modern (mid sec. Temple times) and was non existent in the times of Moses and the first Temple.
Do you know a good book that summaries the opinions and approaches and present a view that is also consistent with the scientific evidences?
