When @CaptainMac posted the 1941 P WDDO-002 I thought to look at my 1941 P LWC's. I found one that has a very fine line running just inside the rim on the obverse. The line goes most of the way around the inside of the rim. Nothing indicated on the reverse. My first thought was coin roller scratch. But, the line is very fine and appears to be raised. It looks like a die scratch or die break.
Your coin also has a little of this going on also: Is this a MAD strike, PMD, or a collar issue? The answer may explain the fine line.
