I had a closer look at the bonds and they were issued by the Central Bank of China, not the Bank of China.
did a search and found it is located in Taiwan. I sent them an e-mail and they sent this reply.
So yeah the bonds are no good.
According to "The Measures Governing the Disposal of Chinese Government Bonds Issued in Legal Currency", publicized and effective on September 6, 1948, all such bonds, including Liberty Bonds, should have been presented to agent banks for redemption within the period from October 1, 1948 to April 30, 1949. As the prescribed period has long elapsed, no more repayments will be made on these bonds.
Your understanding is appreciated.
