A ONE dollar bank note printed a century ago has soared in value to fetch $862,500 at an auction by Spink & Son at the Grand Hyatt Hotel yesterday. Luk Siu-man, wife of Emperor Group chairman Albert Yeung Sau-shing, emerged as the new owner of the note, which had been valued at about $300,000. The note is believed to be the first issued by the Hongkong and Shanghai Banking Corporation in 1872, bearing the serial number 0001 and a printed signature of James Grieg, then chief manager of the bank. An early $5 note issued by the bank sold for $437,000 and became the second highest purchase at the auction. Dated May 1, 1884, the note bears the printed signature of chief manager, T. Jackson, and was estimated to be worth about $200,000. A $10 note, believed to be the first issued by the Chartered Bank of India, Australia and China in 1862, went for $299,000. Also sold at the same price was a $100 Hong Kong bank note issued in 1901.
