1. For badges that have never been seen and have no historical basis, it is necessary to find out its origin, whether all the elements conform to the historical environment at that time, and more importantly, to find out the basic parameters of its manufacture and distribution.
2. For badges that you can't understand at the moment, you must find an expert to identify them. This is especially true for strangers of rare species.
3, identify badges should pay attention to whether the texture is pure, and some need to check the purity of the material. Generally speaking, it is very difficult to forge fake Japanese seals, Republic of China seals and foreign seals, and treasures and fakes can be directly distinguished with the naked eye. First, because most of these seals are made of copper and nickel, they have been forged, made and refined; Second, because this chapter is very precise and rigorous from design to production, the paintings and calligraphy are very exquisite and the craftsmanship is exquisite. In ancient cities, most common fake stamps were in liberated areas and old revolutionary areas, because they were easy to find, monotonous in design, simple in technology and blank in forgery.
4. Be careful about so-called rare or rough products. Look at the material, the history, the craft, the calligraphy, the patterns and the patina. In short, we should be as serious as identifying ancient coins, antiques and calligraphy and painting.
5. For the early badges, we must look at the authenticity of natural patina. Fake badges are mostly made of metal. First, it is necessary to check whether the materials conform to historical characteristics; Second, it is necessary to check whether its natural patina is artificially old. If you have experience in identifying ancient coins, the method of identifying forged seals is easy to master. There are similarities and differences between them.
Second, how to become an expert in badge collection
1, look at the circulation of badges at that time. The collection with small circulation is the most valuable, and the older it is, the faster it will appreciate.
2. Look at the historical significance represented by the badge. It is of great historical significance. If it is a major historical event, badges issued by important historical figures (such as the emperor, Sun Yat-sen, Yuan Shikai, etc.). ) or the royal family, the national government and other authorities have extraordinary significance, and the higher the value of their badges. The medals of major institutions also have a high appreciation space.
3. Look at the texture of the badge. Badges with complete appearance, clear printing and expensive materials also have high collection value.
