Ma'aser Sheini4: 9
כָּל הַמָּעוֹת הַנִּמְצָאִים, הֲרֵי אֵלּוּ חֻלִּין, אֲפִלּוּ דִינַר זָהָב עִם הַכֶּסֶף וְעִם הַמָּעוֹת. מָצָא בְתוֹכָן חֶרֶשׂ וְכָתוּב עָלָיו: ,,מַעֲשֵׂר”, הֲרֵי זֶה מַעֲשֵׂר.
All coins that are found, these are chullin, even a gold dinar with a silver [one] and with [copper] coins. [If] he found among them a potsherd upon which it was written “maaser,” then it is maaser [sheni].
Ma'aser Sheini4: 10
הַמּוֹצֵא כְלִי וְכָתוּב עָלָיו: ,,קָרְבָּן”, רַבִּי יְהוּדָה אוֹמֵר: אִם הָיָה שֶׁל חֶרֶס, הוּא חֻלִּין, וּמַה שֶּׁבְּתוֹכוֹ קָרְבָּן. וְאִם הָיָה שֶׁל מַתֶּכֶת, הוּא קָרְבָּן, וּמַה שֶּׁבְּתוֹכוֹ חֻלִּין. אָמְרוּ לוֹ: אֵין דֶּרֶךְ בְּנֵי אָדָם לִהְיוֹת כּוֹנְסִין חֻלִּין לְקָרְבָּן.
One who finds a vessel, and upon it is written “korban,” R' Yehudah says: If it was pottery, it is chullin, but that which is in it is consecrated. But if it was metal, it is consecrated, and what is in it is chullin. They said to him: It is not the way of people to put chullin into [a thing that is] consecrated.
