This morning, 2 date-off stamps of Mei Lanfang (or a Peking Opera actor) were auctioned for $13.50 and $16.50. One is an actor shaking a fan, and the other is an actor wielding a double sword. Compare the same stamp prices in China to see which market has the higher prices. (I checked it online, and there are very few reference price information or reference books for date-stamps in China).
In short, some foreign philatelic albums are classified by characters, and junior philatelists will find "character stamps" to collect (collect) according to Tu Suoji. Stamps of famous people in each country have great collectible value. Especially before the reform and opening up, there were few opportunities for China to communicate with foreign countries, and there were few communications, so there were few opportunities and channels for foreign philatelists to obtain Chinese (stamped stamps). In short, things are rare and expensive, and there may be a lot of date-stamps on the mainland that cannot be sold at a price, but if you change your thinking and sell them to the international market, you may get a higher price than similar stamps in China.
