'Shekels of Silver' in the Bible

then shall, thine estimate be for the male from twenty years of age even to sixty years of age, yea thine estimate shall be - fifty shekels of silver by the shekel of the sanctuary;

And, if it he from a month old even unto five years old, then shall thine estimate be - for the male, five shekels of silver, - and, for the female, thine estimate shall be three shekels of silver.

And if of the field of his possession any man would hallow unto Yahweh, then shall thine estimate be according to the seed thereof, - the seed of a homer of barley, at fifty shekels of silver.
