According to Huang, no fake tickets have surfaced at the Expo. So what value do the used tickets have for scalpers?

"One ticket may not count, but a collection of one month or six months would be highly valuable," he said.

After being pressed, one of the scalpers disclosed the value the tickets represent. "I believe a collection of the entire 184 days could be worth over RMB 10,000  ($1,470) in the collection market," he said.

Whether or not the scalper was telling the truth, used Expo tickets have more direct benefits.

According to the Expo's official website, ticket holders can receive a 10 percent discount at 30 tourist attractions in Shanghai throughout the Expo at places such as the Science and Technology Museum, the Wild Life Zoo and at the scenic lounge on the 100th floor of the World Financial Center.

Further discounts are also available at other tourist attractions in China, such as the Huangshan Mountain in Anhui province and the Terracotta Warriors in Shaanxi province.
