It’s the first time that the first, second and third series of zodiac stamps are being focused for 36 years’ feelings , called Zodiac Happy Reunion. The complete collection covers a total of 48 stamps (pure gold/silver edition) with prototype, original size and original number of three circles of zodiac stamps. Taking Au.999 / Ag.999 material as the carrier, they are produced by Shanghai Mint Co., Ltd and issued by China Post Group Corporation. Adopting top precious metal double-sided ultra-thin die-casting process and color printing technique, it perfectly re-engraves three circles of zodiac stamps issued from 1980 to 2015.
