The development process of the large bronze medal collection market has mainly gone through the following stages:

Early start-up stage (1980s to 1990s)

Low market awareness: During this period, the market for collecting large bronze medals was in its infancy, and many people lacked understanding of them. Due to the lack of denomination, the large bronze medal was not prominent in the collection field at that time, and people‘s collection focus mainly focused on coins with denomination such as gold and silver commemorative coins and circulating commemorative coins.

The theme and craftsmanship are relatively simple: Early bronze plaques had a relatively single theme, mainly commemorating some common events or characters. In terms of craftsmanship, although there is already some carving and casting technology, the overall level is relatively limited, and the exquisite level of design and production needs to be improved. For example, some early large copper seal patterns were relatively simple and the relief effect was not obvious.

Limited distribution channels: The issuance of large copper stamps is mainly handled by a few mints or related institutions, with relatively narrow distribution channels and small market circulation. The main way for collectors to obtain large copper stamps is through specific channels or dealers with connections to the mint.

Slow development stage (around 2000-2010)

The collection group is gradually expanding: With the passage of time, more and more collectors have begun to pay attention to the unique charm of the large bronze medal. The large volume of the bronze seal provides a vast creative space for designers and carvers, allowing them to fully showcase their artistic talents. Its exquisite design and exquisite craftsmanship have gradually attracted a group of collectors, and the collection group continues to expand.

The themes and craftsmanship continue to enrich: During this period, the themes of large bronze medals began to diversify. In addition to traditional commemorative themes, various themes such as culture and art, scenery, and zodiac animals also emerged, meeting the needs of different collectors. In terms of craftsmanship, the mint continuously improves its technology, gradually applying techniques such as high relief and hollow carving to the production of large copper medals, making the artistic effect of large copper medals more prominent. For example, some bronze zodiac signs use high relief techniques to vividly depict the images of zodiac animals.

Market transactions are gradually becoming more active: With the expansion of the collection group and the continuous promotion of large copper seals, market transactions are also gradually becoming more active. Some postal currency card markets have started to have specialized trading booths for large copper stamps, and the price of large copper stamps has also increased. At the same time, some collectors have begun to pay attention to the investment value of large copper seals, using them as an investment channel.

Rapid development stage (around 2011)

The variety and quantity of issuance have significantly increased: In the first half of 2011, the market for large copper seals was very hot, with new products emerging one after another, and almost a new variety of large copper seals would be launched in one or two days. Various folk commemorative medal factories also actively participate in the production of large copper medals, resulting in an unprecedented peak in the variety and quantity of large copper medals issued. For example, there are more than ten types of bronze plaques with the theme of the 100th anniversary of the Xinhai Revolution.

High market heat and rapid price increase: The influx of a large number of new collectors has driven the heat of the large copper seal market to continue to rise. After many new large copper stamps were launched, the market trading prices quickly rose in a short period of time, even doubling in price, and were able to maintain good transactions.

Market competition intensifies: With the booming market for large copper seals, there has been a significant increase in developers and manufacturers, leading to intensified market competition. In order to gain more market share and support, various developers and manufacturers have begun to focus on the design and innovation of large copper seals.

Adjustment phase (around 2012-2015)

The market heat has declined: In the second half of 2011, due to the adjustment of national macroeconomic policies, the introduction of tightening measures such as banks raising deposit and loan interest rates, and the overall rise and fall trend of the postal currency card market, the large copper seal market also began to show a gradual decline trend. The market performance and transactions of copper seals and new large copper seals are significantly lower than in the first half of the year, and many large copper seals have experienced a decline in transactions.

Market tends towards rationality: After rapid development and market adjustment in the early stage, collectors and investors have become more rational. They place greater emphasis on the quality and collectible value of large bronze plaques, and no longer blindly pursue those with ordinary themes and rough craftsmanship. The market is gradually returning to a state dominated by high-quality large copper seals.

Stable development stage (2016 present)

The collection group has become more mature: After years of development, the large bronze medal collection group has continued to grow and become more mature. Collectors‘ appreciation level and collection requirements for large bronze medals continue to improve, and they pay more attention to the artistic, historical, and cultural connotations of large bronze medals.

Continuous innovation in theme and craftsmanship: In order to meet the needs of collectors, the theme and craftsmanship of the large copper seal are constantly innovating. In addition to traditional themes, some themes with contemporary characteristics and cultural creativity continue to emerge, such as large bronze plaques related to sports events, cultural activities, and so on. At the same time, the process technology is constantly improving, such as using more advanced casting technology, color transfer printing technology, etc., to make the artistic effect of the large copper seal more outstanding.

The market is becoming more standardized: With the continuous development of the market, the large copper seal collection market is gradually moving towards standardization. Some unregulated developers and manufacturers are gradually being eliminated, and the quality of large copper seals in the market has been guaranteed to a certain extent. At the same time, relevant collection associations and organizations continue to emerge, providing a platform for collectors to communicate and learn, and promoting the healthy development of the market.
