How to judge what is written on the copper coin?

The characters on copper coins are usually called face writing or Qian Wen. The vertical lines on the surface are called vertical lines and the horizontal lines are called horizontal lines. The back of money is called back for short, and the words on the back are called back. If there is neither text nor ornamentation, it is called bare back.

If you want to judge what the words on a copper coin are, you can start from the following aspects: First, look at the shape. An ancient dynasty usually formulated very strict style standards when casting copper coins, and left the style at that time on a copper coin. These standards include writing forms and casting techniques. For example, the coins of the Song Dynasty and the Qing Dynasty were completely different in shape when casting, and they were also Kangxi Bao Tong of the Qing Dynasty. Although the styles are similar, different mints cast different styles. If it is five baht or half a penny, due to the limitation of casting technology at that time, you will find that although the overall style is the same, it is unlikely that the characters of each 1 copper coin are exactly the same. Therefore, we need to be familiar with the styles of various mint institutions at that time, so as not to be deceived by some low-end counterfeit money. In addition, the differences of punching, pouring and polishing treatment methods in different historical periods also need to be judged by combining the technological characteristics at that time. Secondly, in addition to the pit, there are many copper coins flowing through the market, and the traces of this circulation are also an important basis for judging the authenticity.
