Stamp price of the founding anniversary of the Chinese Empire

It is from you, my friend. Guardian auctioned a set in 2007 with an estimated price of 5,000 yuan and a transaction price of 6,500 yuan. Moreover, it is only in the middle and high grade. According to the current market price, it is not less than 7000 yuan, but it must be a new ticket. There are also many fake tickets for this set of stamps, and you have to find someone to identify them before selling them.
