The whole country is red.

This stamp is a wrong version of the ticket, because the Taiwan Province Province on the stamp is not red, so it is all taken back, so it is not very popular.

It's very valuable, but it's not like you said, China only has more than 100. Someone used to have four squares.

1998 When I was most obsessed with collecting stamps, this stamp was worth about 1.6 million.

The current value should not exceed 300,000 yuan. As for yours, because it is a letter ticket, the price will not be very high after use. Don't expect too much. In recent years, the postal market has been depressed, and the price of 600 thousand is even impossible for a new ticket.

The man you met dared to ask for 600 thousand without looking at his appearance. He must be an asshole. People who really understand stamps don't want such a price.

The stamps should be the same. Don't move them, they are easily damaged.

Note: The most expensive post-liberation stamp auctioned in China is the military ticket "Blue Army Post", which sold 800,000 around 1994.
