Official Seal of Jin Dynasty

The official seal system of the Jin Dynasty was an official seal system during the Jin Dynasty. The shape and production method of the official seal of the Jin Dynasty were similar to those of the previous generation, but there were some improvements in some aspects. The official seal of the Jin Dynasty was generally square in shape, and the seal button was in the shape of a echelon column. The upper end was engraved with the word "Shang" to indicate the direction of the seal. The official seal mostly used the nine-fold seal script, the strokes turned into square folds, and most of the words were arranged in parallel. On the back of the official seal, there were Shao Fu Jian, the Ministry of Rites, the Ministry of Rites of the Imperial Palace, the Ministry of Rites of each state, the various roads, the government, and the state. The casting and printing were independent, and the unified shape was difficult to continue. In the official seals of the Jin Dynasty, some began to show numbers, which might be related to the increase in the number of seals. However, the specific size and system details of the official seal of the Jin Dynasty still needed further study.

Most of these official seals were square in shape, shaped like nose buttons. The size of the official seal gradually increased during the Sui and Tang Dynasties, and Zhu Wen's small seal script was used as the calligraphy style of the seal. In terms of production method, the official seal of the Tang Dynasty used the welding method, which was to use small copper strips to be welding according to the composition of the strokes. During the Sui and Tang Dynasties, the official seal system also changed. The management of official seals was changed from private ownership to public ownership, and the use and ownership of official seals were separated. The change of the official seal in the Sui and Tang dynasties had a profound influence on the seal system of later generations. However, the search results provided did not provide a clear answer to the specific details and more information about the official seal of the Tang Dynasty.

The official seals of the Song Dynasty were mainly made of copper. Other than the emperor's imperial treasures, which were made of jade and gold, the other official seals were basically made of copper. The size of the printed surface became larger and larger, with a side length of about 45 to 55 millimeters. The outer frame of the seal also became wider and wider. Most of the official seals used the "Nine Stacks Seal Script", which meant that the number of strokes was more twisted. There was a time stamp on the back of the seal, which recorded the time of casting the seal and the name of the casting organization. In addition, the official seal system of the Song Dynasty was also very complete, including the establishment of a special printing agency, the Ministry of Rites responsible for the management of official seals, and the establishment of a strict management system. Generally speaking, the official seals of the Song Dynasty had their own characteristics in terms of form, quality and system.

The value of the official seal of the Qing Dynasty depended on many factors, such as material, appearance, age, and so on. The official seals of the Qing Dynasty were divided into different levels. The highest level of official seals were made of jade. Among them, Emperor Qianlong used 23 jade seals. In addition, there were official seals made of gold and sandalwood. Due to the importance of official seals, the imperial court had imposed strict restrictions on the materials used for official seals.

Therefore, it was impossible to determine whether the official seal of the Qing Dynasty was worth anything.

The highest price of the Qing Dynasty official bronze seal in the auction market was the Qianlong period official bronze seal, which was sold for nearly 1.5 million yuan. The market price of other Qing Dynasty bronze official seals ranged from 150,000 to 600,000 yuan. In addition, the official seals of the Qing Dynasty were printed in small quantities and of high quality, especially the books printed by the Inner Mansion. Because they were only for the emperor and ministers to read, they also had a high collection value. However, the specific value evaluation of the official seal of the Qing Dynasty still needed to consider factors such as version, appearance, content, printing method, and printing quality.

The contents of the Qing Dynasty official seal included the date of manufacture, serial number, manufacturing unit (such as "Made by the Ministry of Rites"), the name of the official office (such as "Department of Promotion and consolation in the car"), and the level of the official office (such as "Third Grade Civil Service in the Capital","Internal and External Military Officers below Third or Fourth Grade").

The characteristics of the official seal of the Tang Dynasty were mainly manifested in the following aspects: First, the size of the official seal of the Sui and Tang Dynasties increased significantly, generally 5 to 6 cm square, and the printed surface completely got rid of the shackles of the "square inch seal". Secondly, the official seal of the Sui and Tang Dynasties was changed to Zhu Wen. This was because paper replaced bamboo slips and began to be printed directly on paper and silk. Zhu Wen was clearer and more eye-catching than white text. In addition, the official seals of the Sui and Tang dynasties were still based on the standard seal script. The seal script was round and vigorous, and the strokes were natural and smooth. The style was relatively free, appearing simple and vivid.
