So far I only talked about basic elements about the paper type.
In this second part, I like to put some other security features in the spotlight.
The first (easy) mark, is the presence of a signature.
Of course signatures can be copied as well, but in combination with other security features, it can help to determinate if the forgery is good or bad (in case of a forgery).
If a banknote is copies with a non corresponding signature/serial number... then the forger wasn't the smartes one.
Let's have a simple look at 3 signatures on Euro notes.
First signature (1) is of Wim Duisenberg, a Dutchman, who became the first precident of the European Central Bank (ECB).
He remained president until November 1, 2003.
