pretty much ANYTHING and EVERYTHING can be counterfeited and copied.
That is correct.
However how well do these copies hold up to even simple scrutiny is of more interest. At an event sponsored where at a talk was given by BoC rep, they showed some counterfeit notes. They were good counterfeits but anyone with even a little knowledge of the security features and making of the notes could lead anyone to know that they were counterfeits.
I suspect that the $1 note from this same vendor when handled at a show did indicate evidence of something not being right.
The bigger question for the $2 note in my mind would be whether they go to this length to do a simple error or in this case a signature-serial combination that makes such a rare note.
CA_Banknotes had rightly picked up the anomaly of the intaglio/offset being out of register at the same time on the front of the note.
