Am I the first to notice there can be significant differences in the toning on Gold-Plated NCLT?
I have one 5 cent from
RCM (Subscription) and another from Canada Post (Clamshell).
If you look at my photo, you'll notice the coin on the right is really dark gold while the coin on the left is a faint gold. It is not the lighting. I noticed it when I put my coins side by side.

Or could this be a case of me having a counterfeit coin? Though I doubt so as I bought them from Crown Corporations.
