. Such coins are offered in sets of 5 by the
Bank of Israel. 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. The Israeli Mint has minted two sets of coins for this purpose: an edition of 20.57 gram silver commemorative coins, five of which would come to 102 grams of silver, and a special edition 26 gram silver commemorative coins, five of which would come to 130 grams of silver. Pre-1936 American
silver dollars (commonly known as
Morgan dollars or
Peace dollars) weigh 26.73 grams of 90% silver content and hence contain 24.06g of pure silver, although such coins have become increasingly rare (modern U.S. coins contain no silver). Four
American Silver Eagle coins, specially minted coins sold to collectors and investors which contain 31.1035 grams of 99.9% pure silver, or five of the above-mentioned specially minted silver coins of Israel are commonly used for
pidyon haben in the United States. One may use
silver bullion as well; it is not necessary for it to be a coin per se. Moreover, it is not mandatory to redeem the son in silver coins, and the ceremony can be held using any movable object worth the same value as five silver coins in the same day, other than
promissory notes, which is not acceptable for the ceremony. Later halachic authorities discuss whether
paper money is included in promissory notes; according to the stringent approach, it is possible that modern coins, which are
fiat money not valued according to their metal value, would be the same as paper money. Although the silver coins are the payment to the kohen according to the
613 commandments and are one of the
twenty-four priestly gifts, they are sometimes returned by the kohen to the family as a gift for the child, although halachic authorities stipulate that, for the
pidyon to be valid, the choice of returning the coins as a gift rests upon the kohen whereas pressuring the kohen to do so would render the redemption invalid.
Pidyon certificate Some kohens officiating for the
pidyon ceremony will present the father with a "
Pidyon HaBen certificate" of the
pidyon transaction, the certificate will usually be framed for display and may serve as a receipt (and evidence) that the transaction was done according to
halacha (i.e. the kohen was not pressured to return the coins), with the kohen and two witnesses ("
Eidim") affixing their signatures at the time of the ceremony. ==See also==
