How much is 5000 shekels of bronze in pounds?

It depends on which shekel (weight unit or currency) you are referring to.

Shekel (sheqel, Akkadian: šiqlu or siqlu, Hebrew: שקל‎, pl. shekels, sheqels, sheqalim, Hebrew: שקלים‎), is any of several ancient units of weight or of currency. The first usage is from Mesopotamia around 3000 BC. Initially, it may have referred to a weight of barley. This shekel was about 180 grains (11 grams or .35 troy ounces). As with many ancient units, the shekel had a variety of values depending on era, government and region; weights between 9 and 17 grams, and values of 11, 14, and 17 grams are common.

Since 1980, the shekel has been the currency of the modern state of Israel.
