Hello all! I'm new to collecting, well at least online... I have a nice US Silver Eagle collection and proof sets, but I recently started branching out and getting some world coins.
My Queen's Diamond Jubilee $20 High Relief coin just arrived from the Canadian Mint earlier today, first I noticed there was no reeding on the edge, which I understand is normal. However the thickness of the edge varies so much. So much that if you took it out of the capsule and set it down, it won't lay flat, it would be on an angle. I didn't take the coin out of the capsule yet, but by approximation w/my calipers on the side the capsule, the left side of the coin has a thickness of 3.27mm, the right side is about 2.53mm, a huge difference.
I'm new to high relief, and I assume this is incorrect and being so, it may be worth it to send it off to NGC for proper grading and marking as a mint error.
Here are some photos
Thoughts?

I took a look at this video on YouTube at about the 1:14 mark the guy makes a remark at how good the quality control is, and then he spins the coin in his hand, showing all sides are even..

I've got something odd here.. Need to find out what it is, and what do I do w/it.. for a mintage of only 7000, this could be rare..
What kind of slab will NGC have? if the slab is opaque you might not be able to see the edge. I don't have any NGC so I don't know. IMO I don't think it would add any significant premium to the value of the coin.
You would have to remove the capsule to be sure but it appears to be a bit of rim finning which can be caused by a high pressure strike, leading to the planchet extruding between the collar and die. https://goccf.com/t/116192

NGC now uses a four prong edgeview holder instead of the old solid opaque insert that completely covered the edge of the coin.
I just dug mine out to look at it. It does seem slightly thinner in the area behind the Queen's head in the high relief portrait. And thickest in front of her mouth. Doesn't seem as dramatic a difference as yours though. Can't quite convince myself that it's not just an optical illusion from the case....
Ok I took another look at it, its certainly not rim finning, as the entire coin is thicker on the one side. Next week I have new coin gloves arriving and i'll take it out and take more photos. Its at the bottom of the capsule and from what I can tell if I was to take this coin out and set it down on a flat surface you would see the coin on an angle. Its that easy to see even through the case.
When I took the photos above, the coin wasn't sitting down all the way to the bottom of the capsule, I tapped it a few times and its settled to the bottom. As you turn it you can clearly see the difference..
I should do that, put it on something that rotates and make a quick video of it...
It looks like all of the major Mints are getting onto the Ultra High Relief bandwagon. It has taken them a bit over 100 years to figure out this commercial niche.
Have you weighed this coin? Looks like the planchet may have been undersized/weight and wasn't pressed into the collar correctly due to the lack of metal in the planchet
