What is the success of RMB rating?

The success of RMB rating is mediocre. China's dry comment on banknotes is very good. Zhonggan Review has experienced appraisers, and its main customers are a series of cultural works of art related to paper money. It has exported two professional rating brands, and there are many agencies in mainland China and Hongkong to provide users with specialized coin appraisal and rating services, so it is very good for China to evaluate banknotes. With the expansion of collection groups and the increase of varieties of gold and silver ingots in past dynasties, the existing rating standards of gold and silver ingots have been unable to adapt to the current market situation. Keeping objective, accurate and professional rigor is the aim of China Gold and Silver Ingot Rating. According to the company's rating big data, combined with the current situation of gold and silver ingots collection, Zhonggan Evaluation optimized and improved the current gold and silver ingot rating standards. In the past, our gold and silver bars' rating standard was based on Sheldon's rating method, which is an international general mechanism currency rating method, that is, the quantitative grading system of coin appearance. Through the rating of gold and silver ingots in the past four years, we have accumulated and used for reference the rating method of hand-made ancient Greek and Roman coins by NGC, the world's largest coin rating company, and combined with the age characteristics, casting technology, hand-made and hand-punched particularity of gold and silver ingots in past dynasties in China, formulated the existing circulation state of gold and silver ingots after they were released from the furnace as the evaluation basis, and added seals.
