100 Yuan - Teller Practice Banknote China Construction Bank

Training notes issued by Chinese state banks for teller instruction are rarely preserved — they exist to be handled, marked, and discarded. China Construction Bank's practice series replicated the physical format and paper feel of genuine Renminbi to train cashiers in detection and counting procedures, but were printed with explicit voiding that rendered them non-negotiable. Most were destroyed at the end of training cycles, which makes any surviving example genuinely uncommon despite their modern origin.

No serial number structure, no People's Bank authorization — these sat entirely outside the formal currency system.
