This is not Hong Kong dollars, but 1 old peso notes issued by Uruguay in 1967, which have stopped circulating. Now the currency circulating in Uruguay is new peso. “BANCO? CENTRAL? DEL? URUGUAY means "Central Bank of Uruguay" in Spanish. The words "Hongkong and Shanghai Banking Corporation" and "One hundred yuan" on the paper money were printed by swindlers.

Many criminals use these invalid banknotes to deceive people. There is no direct exchange rate between the Uruguayan currency and RMB, so the Uruguayan currency, the new peso, is not convertible into RMB, not to mention the obsolete Uruguayan peso.

don't exchange foreign currency you don't understand in the future, so as not to be cheated.
