It wasn't until GrapeCollects posted that RPM link that I ever saw another 1919-S RPM. I wasn't comparing what I had to anything.
I also didn't know that this year and mint was rare for an RPM.
I just thought is was an RPM, under my loupe I can see "something" better than I can photograph.
But from what I'm hearing hear, it most likely isn't an RPM because there's only been that one found, and this "something" I'm seeing is probably nothing.
I thank you all for your feedback, and will move on and keep looking. It's probably just worn and damaged.
