Contemporary religious authorities believe that the "Shekel HaKodesh" (Holy Shekel) of the Temple was larger and of purer silver content than the standard shekel used for trade in ancient Israel. Halakha requires that the coins used have a requisite total amount of actual silver. There are varying opinions as to the correct amount of silver, they fall in between 96.15 grams and 102 grams. Coins which do not contain the requisite amount of silver do not result in a valid redemption.
