The new polymer notes appearing around the world may be more difficult
to counterfeit, but that doesn't deter counterfeiters for long: "An
officer at the Hanoi Branch of the Saigon Industrial and Commercial

Bank on July 26 discovered a counterfeit VND100,000 polymer bank note."
Nguyen Van Toan, Deputy Head of the Vault and Issuance Department under
the SBV said that counterfeit VND100,000 bank notes had been found
before, in March 2006. The SBV later warned the public against the
circulation of counterfeit money and posted instructions to the ways
to differentiate real and counterfeit money on their website
www.sbv.gov.vn

The newly discovered counterfeit VND100,000 bank note was almost
an exact copy of the real note. In the past, counterfeit notes were
easily produced on the old style cotton paper, while the new polymer
material has proven harder to emulate."

"Mr Toan from SBV said that although the counterfeit notes were made
with very sophisticated equipment, they can still be easily recognised.
Mr Hanh from SBV’s HCM City Branch said that the counterfeit bank notes
are identified by the late generation counting machines."

YIKES!!!

I thought it would be a matter of time since Australia made debut in 1988 but who would expect Vietnam would to target such notes!

Actually there was a rumor that the Vietnamese gangs counterfeited Australian 50 dollars bills, so who knows if they are related to the counterfeiting of such Vietnamese dongs.
