Zaizhen’s portrait appears on notes of The Sin Chun Bank (華商上海信成銀行) – the first savings bank in China. The bank was founded in 1906, and issued notes from 1907. It closed in 1913.
The note below is an unissued 10-yuan (10-dollar) dated 1907 in the British Museum collection (1986,0554.101). The note was printed in Japan, and the date is presented in the Chinese style (33rd year of the Guangxu period) and in the Japanese style (40th year of the Meiji era).
Here’s a close-up of the portrait:
Aisin Gioro Zaizhen (1876-1947) was a Manchu prince and politician. The inscription below his portrait on the banknote reads 大清國商部尚書固山貝子銜鎮國將軍載公振 (Secretary of the Board of Commerce of the Great Qing empire, Prince of the Fourth Rank, and Defender General, Prince Zaizhen).
The portrait appears to be based on a photograph (source: Wikimedia Commons)
The image of The Sin Chun Bank was also based on a photograph of the building in Shanghai. The Head Office was at Dadongmen, Shanghai (上海南市大东门万聚码头).
Here’s the photograph (source: 360doc no.37):
Zaizhen’s visits to the UK
Zaizhen (Tsai Chen, Tsai-Chen, Tsai-cheng) visited the UK at least twice. He represented China at the coronation of Edward VII in 1902 – the coronation was postponed owing to illness, and Zaizhen went to Oxford that day instead. He also represented China at the coronation of King George V and Queen Mary on 22 June 1911. Prior to both occasions, The Times‘ correspondent expressed his dismay at the choice of Zaizhen as representative of China.

 “China.” Times [London, England] 22 Jan. 1902: 5. The Times Digital Archive. Web. 5 May 2017 – “I am informed that a son of Prince Ching has been nominated to represent China at the Coronation of King Edward. He is 26 years old, without personal distinction, and is quite unknown. His present rank – a duke of the fourth degree – will be raised to that of Pet-tsze, or prince of the fourth degree. He is a distant cousin of the Emperor, Prince Ching being descended from the 17th son of the Emperor Chien-lung, who died in 1796. It is regrettable that China should be so inadequately represented at the great pageant. The Chinese will inevitably compare to our disparagement the relative rank of the envoy with that of Prince Chun.”
 “China’s First Prime Minister.” Times [London, England] 17 May 1911: 7. The Times Digital Archive. Web. 5 May 2017 – a damning feature on Zaizhen’s father printed about 5 weeks before the coronation: “For years the Prince [Ching] has stood for all that is most evil in Chinese officialdom… his record is always associated with disaster. No constructive statesman, no masterful patriot, he has lived his 73 years with no act of glory attached to his name. Censors have vainly impeached him; the Press never mentions his name but in execration, but he survives it all, and is daily more powerful.”
 G.E. Morrison, The Times Correspondent in his letter to D.D. Braham, 5 Sept 1911, wrote of the “disreputable Tsai-Chen”, that it was “an insult to send such a man to the Coronation”, although the Chinese “sent to the King gifts of quite unusual beauty and value” – see Lo Hui-min (ed), The Correspondence of G.E. Morrison 1895-12 (Cambridge University Press, 1976), p. 623.
