Thanks for the +ve feedback guys!
Continuing with the 1937 set, I'll start with my first Osborne Towers signature which lasted only 2 prefixes (A/B & B/B). While 20,000,000 notes were released this was still during the depression & not a lot of great examples were kept by Canadians struggling to keep food on the table. This is especially true for the mid-higher denominations (which issued less of the first signature) but the $5.00 actually turns out to be the scarcest mid denomination.
1937BC-22a/P-59a TWO DOLLARS:A/B prefix in AU 50 "Original"

B/B prefix in AU 50 "Original"

Both notes are nice but have rounded corners & soft edges.
The 3rd $2.00 note (below) is the 2nd note of the Z/B signature change over (from Gordon Towers to Coyne Towers)

I won this note on
ebay from a US seller who stated it was UNC but it turned out to be lightly pressed & was graded AU58 (no "Original" designation). It is also possible that the note was washed as the colour is much lighter (or it was mounted & exposed to light).
Keep in mind that the paper of the 1937 Series starts out rather dark (almost beige) for the Osborne (a) & early Gordon Towers (b) notes and then becomes a much more bleached white for later Gordon (B) & Coyne-Towers (c) examples.
The back of the $2.00:

(Note how they used the back design seen on BC-7 1935 $10 for this $2.00 now in "brick" orange).
BC-23a/P-60a FIVE DOLLARS:The following Osborne $5.00 is extremely scarce (less than 1 prefix) & I struggled for quite a while trying to obtain one in decent VF condition. I just had lost out on an original VF beauty on
ebay & was in a poor frame of mind when I settled on this BCS VF-20 example:

The note looks washed & has poor corners but otherwise has not bad eye appeal. Charlton states under "TIP FOR COLLECTORS" that the Osborne $5 remains elusive in "original" UNC condition. Most older collectors I've met believed that only a portion of the 8.8M were probably released. (sorry for the small images)
BC-23c/_P-60c FIVE DOLLARS:

This is what the FIVE should look like in AU-UNC. The "Coyne Towers" 3rd signature example has a light vertical centre fold but is otherwise perfect. It happens to be the 2nd note I purchased for my collection when I was a broke teen & I spotted it at a Sears coin shop. It seemed like a small fortune to put away for a note like that (at the time) but I'm very happy I bought this note when I did. It shows like an UNC note but you can see the slight bend in it.
I will cover the $10 & $20 next weekend! Stay tuned & thanks for the feedback!
