One who produces a contract written in Bavel, he collects based on it Babylonian money. [If it were written in] Eretz Yisrael, he collects on it Eretz Yisraeli money. If it were written without specification and he produced it in Bavel, he collects on it Babylonian money; [but if he produced it] in Eretz Yisrael, he collects upon it Eretz Yisraeli money. If it were written in it "money" without specification—then he can collect in any location['s currency] he wants, which is not true for a wife's ketubah [which must be Eretz Yisraeli money]. (Translated from Ehrfurt manuscript).
