Bava Metzia 25A

שלשה מטבעות זה על גב זה, כריכות ברשות היחיד, וככרות של בעל הבית, וגיזי צמר הלקוחין מבית האומן, כדי יין וכדי שמן ⁠– הרי אלו חייב להכריז.

3 coins stacked one atop another; bundles of grain in a secluded area; loaves of a homeowner, as each shapes his loaves in his own unique manner; wool fleeces that are taken from the house of a craftsman, as each craftsman processes the wool in his own unique manner; jugs of wine; or jugs of oil. If one finds any of these, he is obligated to proclaim his find.

גמ׳ טעמא דמצא פירות בכלי ומעות בכיס. הא כלי ולפניו פירות, כיס ולפניו מעות ⁠– הרי אלו שלו. תנינא להא, דתנו רבנן: מצא כלי ולפניו פירות, כיס ולפניו מעות ⁠– הרי אלו שלו. מקצתן בכלי ומקצתן על גבי קרקע, מקצתן בכיס ומקצתן על גבי קרקע ⁠– חייב להכריז.

Talmud: The Talmud infers from the Mishnah: The reason one is obligated to proclaim his find is that he found produce inside the vessel or coins inside the pouch; but if he found a vessel and produce was before it, or if he found a pouch and coins were before it, those, the produce and coins, belong to him. The Talmud comments: We learn from this Mishnah by inference that which A baraita states explicitly in a baraita: If one found a vessel and produce was before it, or if he found a pouch and coins were before it, those, the produce and coins, belong to him. If some of the produce is in the vessel and some of the produce is on the ground, or if some of the coins are inside the pouch and some of them are on the ground, one is obligated to proclaim his find.

ורמינהו: מצא דבר שאין בו סימן בצד דבר שיש בו סימן ⁠– חייב להכריז. בא בעל סימן ונטל את שלו ⁠– זכה הלה בדבר שאין בו סימן.

And the Talmud raises a contradiction from another baraita: If one found an item on which there is no distinguishing mark alongside an item on which there is a distinguishing mark, he is obligated to proclaim that he found both. If the owner of the item with the distinguishing mark came and took his item but did not claim ownership of the other item, the other person, who found the items, acquires the item on which there is no distinguishing mark. This halakha should also apply when one finds a vessel on which there is a distinguishing mark and produce on which there is no distinguishing mark.
