3,520. More About the Coins for Second Tithe

Hilchos Maaser Sheini and Neta Revai 4:10

The coins used to redeem second tithe must be legal tender in that time and place. This is derived from Deuteronomy 14:26: “You shall exchange the silver for anything your heart desires.” We see from this that the silver in question must be suitable for transactions. Coins minted by earlier administrations may be used to redeem second tithe if they are still used as currency.

Hilchos Maaser Sheini and Neta Revai 4:11

One may not redeem second tithe using coins that aren’t in his possession. This is derived from Deuteronomy 14:25: “You shall tie up the silver in your hand.” If one’s money bag fell into a pit but it can be retrieved, he can use those coins to redeem second tithe because they’re still considered to be in his possession.
