(Mishnah): If one was Gozel a coin and it cracked, or Peros and they rotted, or wine and it soured, he pays k'Sha'as ha'Gezeilah.

If he was Gozel a coin and it was disqualified, or Terumah and it became Tamei, or Chametz and Pesach came, or an animal and a person slept with it or served it like idolatry or it (received a minor blemish, and) was disqualified from being a Korban, or if it was being taken to be stoned, he can say 'yours is in front of you.'

(Gemara - Rav Huna): [In the Reisha, a coin that cracked means that] the kingdom disqualified it (so it is totally invalid, as if it cracked);

(Shmuel): It truly cracked (but if the kingdom disqualified it, he says 'yours is in front of you').

(R. Yudah bar Pazi citing R. Yosi bar Chaninah): [Our Mishnah discusses Peros that rotted] due to Kenimah (they are visibly spoiled), but if they rotted due to worms [and on the outside they look fine, the damage is not visible, so] they are like healthy Peros. (We explained this like CHASAM SOFER.)

(Rav Huna): [The Reisha discusses when] the [entire] kingdom disqualified it, but if it is disqualified only in this place, he says 'yours is in front of you.' (The Seifa discusses this.)

(Shmuel): Even if the [entire] kingdom disqualified it, he says 'yours is in front of you.'

R. Yudan did not go to the Beis Midrash. He met R. Mana, and asked what Chidush was taught in the Beis Midrash today. He told him a certain matter. (R. Yosi says that being Metamei Taharos is not considered an action, for the damage is not visible, so he is exempt.)

R. Yudan: Our Mishnah teaches this! [If he was Gozel] Terumah and it became Tamei [he says 'yours is in front of you.' Since the damage is not visible, he is exempt!]

Rebuttal (R. Mana): [Our Mishnah discusses] when it became Tamei automatically. You cannot learn from it anything [about one who was overtly Metamei].

(Chilfai): If one swore to [the Nigzal falsely 'I did not steal your Chametz'] before Pesach, after Pesach he pays proper Chametz.

R. Mana: I went to Kisarin, and I found R. Chizkiyah who taught so in the name of R. Yakov bar Acha.

Question: (Is this a Chidush?!) Does anyone argue with Chilfai, and say that he need not pay proper Chametz? All agree about Chametz, that he pays proper Chametz!
