President Xi Jinping's "Chinese Dream" slogan has aroused excitement among mainland stamp enthusiasts.
A set of four stamps bearing the title "Chinese Dream - Prosperous and Strong Country" and featuring four of the mainland's proudest technological achievements has risen in price, going from a face value of 4.40 yuan (HK$5.60) to 17 yuan in Beijing's Madian Stamp Market in the past week.
The successes displayed on the stamps, issued just before the national holiday, are the Shenzhou X spacecraft, the Beidou satellite navigation network, the Liaoning aircraft carrier and the Jiaolong deep sea research submersible.
According to the Beijing Morning Post, the market price of a small sheet of the series, which consists of four stamps set against a backdrop of outer space and deep ocean, has risen from 6.60 yuan in face value to 23.50 yuan, while the full sheet version has been pushed up from 70.40 yuan to more than 330 yuan.
In Shanghai, the price for the full sheet increased to 280 yuan soon after issue and hit 330 yuan on Sunday, the Shanghai Morning Post reported.
The "Prosperous and Strong Country" collection is one of three "Chinese Dream" series of special stamps issued by the China Post Group.
A total of 15 million stamps will be produced, the Beijing Morning Post reported.
In line with the mainland's current economic slowdown, the stamp market has suffered a downturn after a surge from 2008 to 2011.
However, Jiang Xiaoqiang, a professional stamp collector in Shanghai, said the prices for this collection would continue to grow.
"The collection fits well with the current political climate, attracting a solid demand from stamp collectors." Jiang said.
"The timing is good too, as many companies and individuals liked to buy the stamps and related products as gifts during the National Day holiday."
