Unplated 1943 Cents? Not Unprocessed, Originally Unplated

I had a couple of Original Bankwrapped Rolls of 1943 pennies (NYC Transit Board from the FRBNY), which were disintegrating from moth damage. Going through them, I found what I thought was a really bad plating job: all messed up and kind of Blue-ish, like a reprocessed penny (center coin). That is, until I found a couple of others from the same pair of dies, earlier and later die states, and in a normal silvery-gray color. The center coin looks like it was struck when the dies were Terminal (huge Low Spots o/r, etc), and has dishily bright luster. It's like a Gem BU. I would have thought, had I not known otherwise, that the center coin was reprocessed; but it doesn't have those hallmarks and I took it from a pile of what were OBW Rolls. It's also a mid-die state relative to the other two. There is some micro lemon-peeling of the center coin's obverse surface that isn't seen on the coin on the right, due to plating. Any Ideas?
