The old envelopes after the "Cultural Revolution" are also unusual. The price of a "all mountains and rivers in China are red" real envelope is 65,438+10,000 yuan. Most of the commemorative stamps issued in the 1980s are excellent, and the old envelopes with these stamps are also unusual, especially the old envelopes with higher face value, such as registered letters, express mail, airmail and foreign countries, whose value is not even lower than the new stamps.
In addition, books and newspapers are also valuable collections. Rare books of ancient books are hot spots in collection, especially books, newspapers and periodicals with small circulation, special distribution background, important research value and special commemorative significance printed with special materials should be carefully preserved. With the development of society and the continuous improvement of material and cultural life, all kinds of "fever" are quite popular now and gradually become a trend. Some newspapers collect the first, last and extended issues, while others collect festivals and color editions. Although expired newspapers are a pile of waste paper in the eyes of ordinary people, they may be rare treasures in the hands of collectors.
