1. Revenue stamps counterfeits
Revenue stamps are not left out of interets of counterfeits. Fraudsters show considerable sklil here as well, and the laymen has no chance of distinguishing a well-made countrefeit from the real one. Paper is used for the production of stamps, which looks very believable and stamps can be glued after moistering. What is not perfect about stamps is the perforation. Stamps are supplied in sheets. The perforation that separates individual pieces is regular in genuine sheets, which is a problem in counterfeits.

Experts from the Institute of Criminalistics examined alleged euro banknotes that were all black. The fraudsters passed them off to the victim, saying that they were modified banknotes which had been imported from Africa and the black coloring was supposed to prevent their detection during transport. Along with the banknotes, they also sold the victim a special solution, after the application of which the banknotes were supposed to regain their shape.Examination showed that these were worthless black papers cut to the size of paper euro notes. The victim suffered damages of several thousand euro.
