This just in from the AP:
With its meticulous criminal craftsmen, cheap labor and, by some accounts, less effective law enforcement, Peru has in the past two years overtaken Colombia as the No. 1 source of counterfeit U.S. dollars, says the U.S. Secret Service, protector of the world's most widely traded currency. ...
Over the past decade, $103 million in fake U.S. dollars "made in Peru" have been seized nearly half since 2010, Peruvian and U.S. officials say. Unlike most other counterfeiters, who rely on sophisticated late-model inkjet printers, the Peruvians generally go a step further finishing each bill by hand.
We've reported a few times on counterfeit dollars.
A while back, we talked to Ma Young Ae, who used to live in North Korea, where printing counterfeit dollars is a government-run business. Ma helped the North Korean government export counterfeit dollars them to China
Also, we devoted a whole show to the one, family-owned company that for more than a century has made all the paper that real dollar bills are printed on. That paper is made mostly from cotton and, apparently, it's one of the few things that separates real bills from fakes.
As the AP reports:
For all their skill, says Portocarrero, Peruvian counterfeiters' handiwork will always get tripped up by the infrared scanner banks used to authenticate currency. That, he says, owes to their continued reliance on standard "bond" paper, the variety used by consumers that is available in stores and that easily disintegrates when wet.
If they were able to obtain "rag" paper, the cloth type used for banknotes, all bets would be off, Portocarrero said.
"The day they get it and perfect the finish a bit more, (their bills) will go undetected."
