I really don't understand this thread but I could stand an education.
Are you claiming that this is some kind of an error?
Couldn't it be just normal variation between two different dies that were used to strike two different coins?
Thanks!

that is correct westernsky. as you can see the to C.s in canada are a different size. I started to check alot more coins. I even have checked different coins from the NCLT group. I have seen a few variations there as well. since the ottawa mint has changed the pressing rules last september. they did that because of the new presses they installed. I decided to start checking more coins. I have found more variety in the issues. I mean all issues

It looks like a doubled die?

If it takes a microscope, a computer, 40X magnification and hand-placing an overlay from a computer screen, then I don't consider it anything close to a variety. Taking the thin blue line at 12:00 and tweaking the most-visible image slightly clockwise at the top, everything should just about match up. I'm an old dog looking at a new trick and I hold very little credence in these overlays.
The same hub stamps out or makes XX working dies, each identical except for small tolerances due to striking pressure and alignment. I trust it more than a manually placed overlay into a computer.
Now I'm not disputing what your microscope overlay shows, it's just that we differ on what constitutes a "variety". A variety, in my mind, is something that the mintmaster or foreman on the floor INTENTIONALLY changes on the working die(or hub) to modify what it was before.

Is there any reason the overlay can't be off by just a little bit?

Rocky: Your efforts to overlay similar coins to show anomalies is admirable and really noteworthy. However, there still may be a few things to consider when posting visual differences via overlay. As I have said before, it is accurate only if taken by the same camera, with the same settings, the same lighting, and identical rotational placement. More important is to ensure that the two photos are taken with the same focus, the same magnification and most important, the same perpendicular angle and depth. Even the differences between the strike of the planchet or the hub will show minute differences. I applaud you for your efforts, but a few bugs still need, I think, to be worked out.
