2020 D Quarter Salt River Bay - Missing Clad Layer?

Quote:
I could immediately tell it was a genuine mis-annealed planchet because: Every single 'mis-annealed' coin that someone has shown me at a coin show, or in an email, that turns out to be environmentally damaged or played with, has a darker duller surface than it should have, AND every single non-error has the same dark color on the reeded EDGE of the coin. See the edge photo (#3) - it looks like a normal BU Quarter - the copper core shows a nice normal red color - that's because although the planchet itself (on a genuine mis-annealed planchet) would have the dark color on the smooth edge, once it's struck in the collar, and ejected, that dark color is removed from the reeding due to the ejection of the now-coin from the collar. (I could also tell it's real from the surfaces themselves, - although mis-annealing leaves a range of 'darknesss', seeing the reeding as a normal red copper color is one of the keys to know it hasn't been played with)
