The image is a circular plaque with a gold-colored background and black text. The text is written in Chinese characters and appears to be discussing the manufacturing techniques of Chinese currencies. The plaque is circular in shape and has a black border around the edges. The title of the plaque is "Manufacturing Techniques of Chinese Currencies" and it is written at the top in large, bold letters. Below the title, there is a subtitle in smaller, black text that reads "The techniques used in the manufacturing of Chinese metal coins and Chinese paper money are important components of Chinese monetary culture. Bunch-casting, stacking-casting and sand moulds casting were used after another in ancient metal coin making, and the western coin mining techniques were commonly adopted in modern coin production. Later, in the printing of paper money, xylography, copperplate, lithography and machine print were applied successfully."
