Why is Tang Xianzu's gold and silver commemorative coin set so difficult to rise? The same circulation is 10000.

Although they are both outstanding figures, Tang Xianzu is a historical and cultural figure and Sun Yat-sen is a great man series.

Moreover, Sun Yat-sen's gold and silver coins and ordinary commemorative coins were issued at the same time, belonging to one set, which increased the popularity of Sun Yat-sen's gold and silver coins. Because the United front work needs to be affirmed, like the G20, a considerable part of it was given to the people of Taiwan Province Province as a gift by the Taiwan Affairs Office. Moreover, the anniversary of Sun Yat-sen's birthday150th anniversary is commemorated on both sides of the Taiwan Strait, and commemorative silver coins are also issued in Taiwan Province Province, and our gold and silver coins for Sun Yat-sen's birthday150th anniversary are also sold to Taiwan Province Province, so it is impossible for the mainland to reach 10000 sets.
