Out of this 4 year mint set, why is the 1981P (red highlight) set not toning like the others? Wash? Packaging? Contamination? I say not the alloy because the 81 D is also better out of the 4 years but not as bright as the P. 4 sets- 78/79-worst... 80-better... and 81-best with 81 P by a landslide ... ! The image white balance is flawed. Trust me, the 80s are not as bright as the 81s and the 81p actually looks "mint". All of the copper looks similar but the clads have noticeable bronze tones.
