Chinanews, Beijing, December 27 – Liu Gang, 50, a resident in the Fangshan District of Beijing, is thoroughly worn out in his attempt to find out the authencity of a 500,000-pound certificate of deposit inherited from his father.According to the certificate, the sum was deposited at the Bank of England in 1936, at an annual interest rate of 25%. That is to say, the certificate might be worth several hundred million pounds by now. However, the authenticity of the certificate is yet to be confirmed.Liu showed this certificate to our reporter, which is placed between two glass panels. It is a little torn in the rim, and it is dark-brown in color. The bankbook is printed with ‘BANK OF ENGLAND’ and “500000 POUNDS”. On one side is a pattern of an eagle pecking at a snake in the center. On the other is the picture of a building. There is also a head portrait on either side.Liu said that his grandfather won the money from a Hong Konger via gambling years ago, but LIu had not realized the value of the certificate until 2003, when a friend of his told him so. Liu then quit his job and sold his house, trying to withdraw the money, but all his effort has been in vain so far.
