A status on on the social site Facebook, is warning everyone to look out for the counterfeit €50 banknotes. According to the person who wrote the warning, at present, in the market, one can find €50 fake notes that are identical to the original ones.
The person goes on to say that these counterfeit €50 notes, have both the watermark and silver lines at the side. It seems that even if use the marker dedicated to check whether the banknotes are counterfeit, does not distinguish the banknote as being false.
Apparentely, the only way to identify counterfeit notes from one original, is to feel the lines on paper. If they can be felt, the €50 is original, otherwise it is not.
