Thousands rushed to get their reward with their bottle caps worth a million pesos (about US $40,000) each. But Pepsi wouldn’t pay. The company said there was a mistake. The numbers on the caps did not include a security code (保险号), so the caps were not really winners. Up to 800,000 bottle caps had the number 349. Pepsi has spent millions of dollars on the problem.

From the passage we can guess that peso is ______.
