We will never know for sure how much gold the Jerusalem Temple contained and exactly where it was displayed, internally and externally. It is generally known that Josephus occasionally exaggerates, but that a large amount of gold was displayed in the Jerusalem Temple, appears to be a reasonable suggestion if we also take other historical sources into consideration.For more on ancient real (?) gold and other treasures possibly associated with the Temple, as well as legendary gold and treasures definitely associated with it, see here and links.
