100 Dollars - Teller Practice Banknote

Chinese banks periodically issue polymer training notes for teller education — staff practice handling, verifying, and processing notes on material that mimics real-currency feel without introducing genuine legal tender into the training environment. These are institutional items, not issued through public channels, and they circulate only within bank branch training programs before being destroyed or archived.

Polymer substrate here is the point of interest: China began expanding domestic polymer printing capacity significantly after switching its 2019-series Renminbi to polymer for lower denominations, making in-house production of training material on the same substrate a practical extension of that infrastructure.
