[If] one changes [a silver] sela of maaser sheni [into copper coins], in Jerusalem Beis Shammai say: [He takes change] for the entire sela [in copper] coins. But Beis Hillel say: [He takes change] for [one] shekel [of the sela in] silver and for [the other] shekel [of the sela in copper] coins. Those who debate before the Sages say: [He takes change] for three dinars [of the sela in] silver and for [the remaining] dinar [of the sela in copper] coins. R' Akiva says: R' Akiva says: [He takes change] for three dinars [of the sela in] silver, and for the fourth [dinar of] silver [he takes] for a quarter [copper] coins. And R' Tarfon says: [For the fourth dinar he takes] four aspers of silver. Shammai says: He should leave [the sela] in the store and take [successive amounts of] food corresponding to it.
