I recently purchased this 1942-P Mercury dime and after carefully placing it in a Quadrum capsule, I noticed that the reverse is rotated by a little bit. The obverse appears to be straight (i.e. the letters/words appear to be parallel with the bottom/top edges of the Quadrum), while the reverse looks as if it'll remain rotated even if the obverse's misalignment is slightly corrected. I'm confident that it is a rotated die, but just to make sure while I ask my next question... And, do you think this qualifies as an FSB? The central bands appear to have a straight indentation, but there looks to be some bag marks around it - I'm unsure if the center line is interrupted. As a comparison, I show the other bands to see how well the central bands are split (the center bands aren't as good, but it's not merged or completely interrupted - somewhere in the middle). As an aside, there's also a very subtle rainbow bullseye toning on the reverse near the rim, while the center area has a solid color, which adds a nice touch and my photos don't do the coin justice. Thanks in advance!
Looks like about a 5° rotation, which is within the "normal" range. I'm going to say no to FSB, too. The second picture from the bottom looks like they come together here and there.
