I have a very nice (maybe MS)1922 Canada 5¢. I looked it up in my Charlton Catalogue and apparently whether it is "flat" or "concave" has a significant effect on its value.

The guide shows a picture of each variety, but the difference between the two is vague. Yes, the concave appears to be more deeply recessed by virtue of the shadow cast by the rim, but lighting for the photograph can vary this shadow, so it is very difficult to make this determination based on this feature. If I hold it one way it looks like the "flat" but if it tilt it just a tiny bit it looks like the "concave".

I also noticed that the 2nd "2" (of the date) in the photo of the "concave" version looks weaker than the "flat" one at the left end of its top. Is this an attribute that differentiates the two...or is the coin in the photo just worn there?

Are there any other tips you can provide on how to differentiate these 2 varieties?

I can (and will) post a photo of my coin, but knowing which attributes play a part in differentiating the two will help me know how to take the photo to accentuate these features.

Thanks,

Doug

The concave variety is differentiated at the rim. If, where the rim meets the surface of the coin, there is a reasonably crisp right angle at the point of meeting, this is the non-concave version. If, where the rim meets the surface there is no distinguishable right angle, but instead appears filled in, then this is the concave version.

That sounds about right to me, and there's nothing I can post to illustrate the difference further.
The flat die version is priced significantly higher in the higher grades: MS60 concave: $65, MS60 flat: $150 (Charlton's 2008).

Looking at the two samples here, the Flat (also called Far Rim) and Concave (also called Near Rim) can be distinguished by the 'S' in relation to the rim.

I also have a Certified Flat Rim (FR) that looks exactly like the one on the right however I can't provide a clear image because it is in a slab.

I can't tell one from the other in the date photo, but the edges in the "S" photos, are very clear. Thanks for the info. I'll keep it handy for when I finally get to my 5-cent coins.
