As someone interested in design of bank notes I have been interested in the issue of varnish on the bank notes.
Previous PostsThere has been various posts from the 2006 to 2007 time frames dealing with varnish mostly on the upgraded $5 notes with security.
http://www.cdnpapermoney.com/forum/index.php?topic=3937.msg26759#msg26759In one of the topics there was also some discussion about $10 BTG changeover and one of the members speculating that it would have varnish:
http://www.cdnpapermoney.com/forum/index.php?topic=4972.msg28074#msg28074I am hoping that someday I might get around to documenting Canadian Bank Note Design beyond what is captured in the current publications. While this may not be significant for collectors I do believe it is significant for numismatics.
Full Varnish and Partial Varnish - There is nothing like no varnishIn this regard I have made following observations:
All notes of journey series have varnish. Some have partial varnish and some have full varnish. If there has been notes with no varnish then they are either errors or possible test notes.
The presecurity $5 and $10 journey had partial varnish which incorporated a feature that impacted the visual elements of the note.
The $20, $50, $100 journey all have partial varnish.
The upgraded $5, and $10 journey notes with security either have ranges with either partial varnish or full varnish.
The $5 upgraded notes have been well documented in this forum. The transition point for the BABN prefix was AOG. Thereafter all the prefixes have full varnish. For the CBN prefixes all of them have partial varnish.
$10 Journey Series with Full and Partial VarnishI could not find discussion on the $10 upgraded notes. I get a feeling that since this was not being considered as a variety from the $5 experience, most people did not pay much attention to it as it would not mean much to a collector (I am guessing). However I have found that starting with BTG and going as far as 2008 BFH the $10 upgraded journey notes have full varnish. From 2009 BFH changeover to BFW the notes have partial varnish. The notes from BEU to 2005 BTF changeover have partial varnish. I have not been able to check any2007 BTF notes for the varnish condition however I am guessing that ALL BTF (2005 and 2007) are partial varnish.
I have come to this conclusion about BTF because just like prefix AOG the prefix BTG has a range with partial varnish and a range with full varnish. I have noticed that in the BTG the partial varnish at least goes as far as 2.0.
Maybe you can helpI would appreciate hearing from anyone who has observations regarding the varnish in light of this post. In particular if you have 2007 BTF and BTG I would appreciate if you can check if the have full varnish and provide the serial number. I am trying to establish the point of change in BTG. In the case of 2007 BTF and BTG the partial varnish in my thinking may have been an oversight.
Also I have read somewhere that the partial varnish on all journey notes was applied in an area on the back of the note stretching from the top left to the top middle mostly to provide durability for the tactile feature. Unfortunately I cannot find this information. If you have any thoughts on it please share that.
