Expo '70 Gold Cups - Set of 2 From my mother's collection. They were never displayed, and have been kept in a drawer for many years. They are unused, but there is some slight soiling. 24K GP These are commemorative gold cups from the 1970 Osaka Expo. The gold cups are 5cm in diameter, and the box is 15cm x 7.5cm x 4cm. Thank you for looking.
