CHINA--REPUBLIC. Central Bank of China. 500,000 Yuan, 1949. P-423A?.Face and back design trial proofs. A very interesting piece which shows with SYS at upper left in favor of CKS who is found on the issued notes of this series date. Seen with primary design only with back and face both printed in a dark brown hue. A horizontal fold on the face design is observed while the back design is seen with mounting remnants at the verso and similar horizontal fold. The first we have even seen and surely an item which will be eagerly sought after by advanced collectors.About Uncirculated
