To commemorate the completion of one of the main venues for the 29th Olympic Games, the "China National Stadium," the Organizing Committee of the 29th Olympics, authorized by China Gold Coin Corporation and the China Banknote Printing and Minting Corporation, jointly issued the fourth group of "Beijing Olympic Gold."
In the display cabinet at Beijing Zhongyou Gold Shop, this set of collectibles is showcased. The front pattern features a partial bird's-eye view image of the "China National Stadium," available in five specifications: 1000 grams, 500 grams, 200 grams, 100 grams, and 50 grams, with a limited issuance volume. This group of Olympic Gold, building upon the color printing techniques used in the first three groups, also employs various processing methods such as intricate engraving, sandblasting, reverse sandblasting, and laser engraving, offering a refreshing new look.
