Complete Letter Set 僑批三件套 - 僑批、回批、票根
Every remittance made by an emigrant through a letter/remittance agency is tracked by a trail of paper. This begins when the sender is issued a serial-numbered receipt by the letter/remittance agency overseas that accepts his remittance and letter. The same serial number is attached to the letter and a blank return letter, which is filled in by the family to confirm receipt of the fund. The cycle is completed when the sender is finally given the return letter.A complete set of letter, receipt and return letter has rarely been acquired by collectors since this requires not only for the family to retain the letter, but also the sender to keep and bring home the receipt and return letter when he eventually decides to return.
