You can not take the rest of the Canadian notes off, only the serial #, the Aussie notes showed some experiments were the whole side of a note is whipped clean, so I presume our notes use a different ink
Canadian Polymer bank notes and Aussie Polymer bank notes of current generation are essentially printed using the same sequence. This is well published data and there has been ample written on it from the Banks themselves.
The essential sequence is as follows:
Substrate receives opacifying layer (this is white in colour)
The hologram is applied
The litho printing is done
The Intaglio is applied
The Serial number is applied
The varnish is applied on both sides of the note. The only place varnish is not applied in Canadian notes is over the hologram near the clear window and the frosted window. The process of application of varnish is similar to litho printing.
Bottom line - Yes you can carefully remove the serial number only but the varnish also comes off. There is no way to take out any ink from the polymer without taking the varnish off.
When you see the note without the varnish you can easily tell the difference.
There have been many errors of serial numbers that are legitimate and can be found in the $50's printed by BAI. They happen at specific PN's and in specific ranges of serial numbers.
Here is an example of one from AMF prefix which can be found on PN 94 in a wide range. If you track the serial numbers then you can see where the print head started to wear off and where it was the worst before it was fixed.
With a note in hand you will be able to see that the varnish is intact. There is other evidence in this image which leaves no ambiguity that this was done at the printing stage and not after.
