Shekalim5: 5
מִי שֶׁאָבַד מִמֶּנּוּ חוֹתָמוֹ, מַמְתִּינִין לוֹ עַד הָעֶרֶב. אִם מָצְאוּ לוֹ כְּדֵי חוֹתָמוֹ, נוֹתְנִין לוֹ; וְאִם לַאו, לֹא הָיָה לוֹ.  וְשֵׁם הַיּוֹם כָּתוּב עֲלֵיהֶן מִפְּנֵי הָרַמָּאִין.
[If] someone lost his token, they would have him wait until the evening. If they found [surplus funds] for him corresponding to his token, they would give him [his nesachim]; but if not, nothing was [given] to him.  They were inscribed with the date because of the deceptive ones.
