The raw materials 38:21-31

Moses also recorded an estimate of the amount of metal used (38:21-31). Coined money did not exist until the seventh century B.C. when the Lydians in Anatolia (modern Turkey) invented it. Consequently the shekel Moses referred to was a measure of weight (not quite half an ounce) rather than a measure of value.⁵⁴³The materials included slightly over a ton of gold (v. 24), almost four tons of silver (vv. 25-28), and about two and a half tons of bronze (vv. 29-31).
