1. The crown number of RMB banknotes is one of the measures taken by the People's Bank of China to control the production and management of RMB, which is constantly adjusted and changed according to the needs of RMB printing and management.
2. Double crown number refers to the crown number that is the same as AA, BB, CC and DD letters. For the first time, the fourth set of RMB crown characters formed a double crown number series in the form of capital letters.
3. As we all know, there are 26 capitalized English letters, and more than 600 different crown numbers can be obtained by permutation and combination, among which there are only 26 double crown numbers in theory. Besides the double crown VV crown number (undisclosed) and EE crown number (joint note crown number), there are 24 double crown numbers, accounting for only about 4% of the total crown numbers.
Moreover, with the consumption of market circulation, the stock of paper money with double crown number is even rarer than that with ordinary crown number. In addition, the double crown is more in line with the traditional concepts of China people, such as "in pairs", "yes-man" and "double happiness". Therefore, the price of double crown banknotes is higher than that of ordinary crown numbers.

The meaning of the crown number:
In addition to Chinese characters, minority languages, Chinese Pinyin and Braille, the fourth set of RMB main currency also includes crown numbers and numbers used to control the printing quantity and anti-counterfeiting function of various tickets. Crown, which means first, is also called "prefix", that is, a symbol printed in front of the ticket number to indicate the batch number and printing quantity of various tickets.
Of the five sets of RMB banknotes issued by the People's Bank of China, the first three sets all use two or three different Roman numerals (I, II, III, IV, etc. ) as the crown word, and the fourth set of RMB is changed to two identical or different Chinese phonetic alphabets as the crown word, while the circulating commemorative banknotes for the 50th anniversary of the founding of the People's Republic of China only use one Chinese phonetic alphabet as the crown word.
The number is also the number of printed votes, which is the specific number in each crown word batch number. Generally, Arabic numerals are used to arrange the numbers, one for each vote, and the numbers in the same crown batch number are generally not repeated. It can be seen from the number of digits of banknotes that the greater the number of tickets printed by this group of crowns, that is, the more digits, the greater the printing volume, and vice versa.
