[If] one changes a sela of maaser sheni in Jerusalem [into copper coins], Beis Shammai say: Coins for the entire sela. But Beis Hillel say: A shekel [of the sela in] silver and a shekel [in] coins. Those who debate before the Sages say: For three dinars [of the sela] silver and for [the remaining] dinar coins. R' Akiva says: Three dinars [of the sela] silver and the fourth [dinar] coins. R' Tarfon says: [For the fourth dinar he takes] four aspers of silver. Shammai says: He should leave it in the store and eat against it.
