I have started to check my supply obtained during my Dec 24 visit at the Richmond Hill facility and here are a few interesting varieties on the "permanent" one.
First, in a series of 50 (all ending with numbers 2823, the 1st one that came out shows the small permanent on the top stamp (MacDonald one). 2nd strip appears normal as the other 8 strips
I then ordered a strip of 5 and on this one, the small permanent lettering appears on the 2nd stamp (Thompson)
Since this has also been reported on the Vancouver ones (18 digits and the Richmond Hill (14 digits), it tells me that there will likely be many many varieties to collect in these issues.
I also have a set of the Vancouver with the ski slopes that I can show later (11 printed on the LL bottom of each strip).
As for used copies, I can offer a few Richmond Hill permanent ones on an envelope, (issued from Ottawa, in exchange for same from the Edmonton or Vancouver ones. This will become handy overtime, as I think early use of those would be relatively scarce.
