Might it not signify small change? — Small change is not made of gold. '"Gold for denarii" [signifies] gold of the value of no less than two silver denarii.' Might he  not have meant, broken gold [ware] of [the value of] two gold denarii.? — Abaye replied: The holder of the bond [must always be] at a disadvantage.  If  so,  [the same principles should be followed in] the former [cases] also!  — R. Ashi replied: [In the] first [cases] denarii was written; [in the] last, dinrin was written.  And whence may it be deduced  that there is a difference between denarii and dinrin? — for we learnt:  A woman who had  five doubtful confinements  [or] five doubtful issues,  brings one offering  and may  [subsequently] eat of sacrificial meat. She is not obliged, [however, to bring] the rest.  [If] she had  five certain confinements [or] five issues, she brings one sacrifice and [may subsequently] eat of sacrificial meat but is [also] obliged to [bring] the rest.  It once happened that [the price of a pair of] birds  in Jerusalem had risen  to gold denarii.  [Thereupon] R. Simeon b. Gamaliel exclaimed, '[By] this Temple!  I shall not go to rest this night before these [can] be [obtained] for silver denarii'.  He entered the Beth din and issued the following instruction:  'A woman who had  five certain [child] confinements, [or] five certain issues, brings one sacrifice and may [subsequently] eat of sacrificial meat, and there is no obligation upon her to bring the rest'.
