I just came to Hong Kong for a longer period of time and I have a trouble exchanging some of the USD I brought. This first happened at the DHQ, when I was asked to exchange one bill for a newer one. Today I tried to exchange some USD for HKD in exchange office near Western Market but they also refused to exchange the pre-2013 bills. The pre-2013 bills are the ones without blue band and goldish-brownish emblem near the blue band on the front of the bill. Do you have some idea where can I exchange them? Will banks accept them to deposit them at an USD account? I am thinking about opening an HKD and USD account at HSBC when I get my HKID.
