2009年汇丰银行20元，幸运号AA000001，PMG 64，2009年"双A"字轨的佳品，编者推测2003年AA000001号由银行保存，不会流出市场，藏家难以寻得。The Hongkong and Shanghai Banking Corporation, $20, 1.1.2009, a superb alphanumerical lucky number AA000001, (Pick 207f), PMG 64 Choice Uncirculated, the repeated AA prefix in the 2009 issue but still a fantastic note. The cataloguer will make the surmise that the 2003 AA000001 is kept by the bank and will not be avialable for private collectors.
