Bouvier's Law Dictionary, Revised 6th Ed (1856):

TELLER. An officer in a bank or other institution. He is said to take that
name from tallier, or one who kept a tally, because it is his duty to keep
the accounts between the bank or other institution and its customers, or to
make their accounts tally. In another sense teller signifies a person
appointed to receive votes. In England the name of teller is given to
certain officers in the exchequer.
