Mishnayos Shekalim Perek 5 Mishnah 4

One who seeks libations for his offering goes to Yoḥanan, the official who was responsible for the seals, and gives him the appropriate sum of money and receives a seal from him. With that seal he subsequently comes to Aḥiyya, who was responsible for the libations, and gives him Yoḥanan’s seal and receives his libations from him. In the evening, Yoḥanan and Aḥiyya would get together to reconcile their accounts, and Aḥiyya would take out the seals he had received and accept the money Yoḥanan had received in exchange for them. If the money was less than the value of the seals, they were less to him, i.e., Yoḥanan would bear the loss, and Yoḥanan would have to pay the difference to the Temple treasury from his own property. And if there was some money left over, i.e., the total money was greater than the value of the seals, they were left over to the benefit of the Temple treasury of consecrated property, as the Temple treasury always has the upper hand.
