He took the crown of their king from off his head, and its weight was a talent of gold, and in it were precious stones; and it was set on David’s head. He brought out the spoil of the city, exceeding much. Bible

“a talent of gold.” Although the word “talent” was used in different cultures, the weight differed. An Israelite talent was 75 pounds, whereas a Babylonian talent was 66 pounds. Thus, this crown was 75 pounds.
