The olive-colored Queen Victoria’s head was issued in 1864 with the face value of 96 Hong Kong cents. Initially it should have been printed in a brownish-grey tone. But due to some error the 52 of the overall number were printed in olive color. The watermark was wrongly styled, and the word “CC” was printed in the wrong place. As of today only 40 pieces of the olive-colored Queen Victoria’s head can be found, and only one block of four exists today. It was auctioned for $820,000 at Spink auction that took place in Hong Kong, in 2012.
