Charles Ellicott Commentary 1 Chronicles 29:7

"and they gave for the service of the house of God of gold five thousand talents and ten thousand darics, and of silver ten thousand talents, and of brass eighteen thousand talents, and of iron a hundred thousand talents." — 1 Chronicles 29:7 (ASV)

And gave ... of gold. — And they gave ... gold, five thousand talents; between thirty and forty million sterling (!).

Ten thousand drams. — Rather, Darics. The Daric (Greek, Δαρεικὸς) was a Persian gold coin, value about one pound and two shillings, first struck by the great Darius, son of Hystaspes (B.C. 521-485). It remained current in Western Asia long after the fall of the Persian Empire.

The Hebrew word (’ ădarkônîm) occurs again only once, namely, at Ezra 8:27, where it clearly means Darics, and is so rendered by the Syriac (dărîkûnê.). The darkôn (or darbôn) is mentioned in the Talmud as a Persian coin. The chronicler, or his authority, has evidently substituted a familiar modern term for some ancient expression of value. No real coins are mentioned in Scripture before the age of the exile.

Silver ten thousand talents. — About £4,000,000 in modern value (see 1 Kings 10:21; 1 Kings 10:27); or, according to Schrader, who argues from Assyrian data, £3,750,000. The value of the bronze and the iron must have been much greater then than now. (See Note on 1 Chronicles 22:14.)
