A man who dies and leaves sons and daughters, when the property is large, the sons inherit and the daughters are fed and supported. How do the sons inherit? They [the court] don't say: "If their father were still alive, he would have given them X"—rather, they see each one as if he were their still living father [at the same social status], and pay them. How are the daughters fed and supported? They don't say: "If their father were still alive, he would have given them X"—rather, they see them as they are [now in social status] and so how much they need support, and pay them. Rabbi says: Each of [the daughters] takes a tenth of the property. Rabbi Yehudah says: If he married off his first daughter [with a certain dowry], he has to give to the second like what he gave to the first. They said to him: There are those who marry off their daughter and receive money, and those who marry off their daughter and pay after her money. And so Rabbi Yehudah used to say: One who marries off his daughter without explicit [stipulation of a dowry], he should not give her less than 5 selaim, for in the old days that was enough to buy for her everything she needs.

She agreed to bring in for him [in the dowry] 2 selaim (=4 dinarim), they become 6 dinarim [that he has to pay her back in the event of death or divorce, he has to compensate her +1/2 since he has had use of the dowry in the meantime; see Mishnah Ketubot 6:3]. Whatever the groom agrees [to bring in as his dowry in the ketubah], he puts it in at a value of -1/5, except for the 200 zuz for a virgin or 100 zuz for a non-virgin. (This is probably about evaluating the value of objects he brings in; see Mishnah Ketubot 6:3.) She agreed to bring in for him gold, the gold is like vessels [i.e. are evaluated, so have the -1/5 modification in the ketubah]; golden dinarim, the gold is like money [i.e. are not evaluated, so have the +1/2 modification in the ketubah]. Said Rabban Shimon ben Gamliel: And this is true for any place where the custom is not to exchange golden dinarim [for smaller currency], [but in a place where this is not true] they leave them the way they are and the gold is like vessels.
