1956d rpm?

DO you see this vertical bar? I think this is a RPM, but I can't find any matches. Any thoughts?

I see the bar, but like you I cannot find a match to anything posted elsewhere or in my library.

Thanks Jean, I'm glad I'm not seeing thing. Maybe it's a new discovery.

Dave, I've been caught on those before. They are usually part of the original mintmark that is starting to wear. Causes a lower impression that looks like another mintmark but is not. I've canned soooo many 80's Thought to be RPM's that are all this type of wear in the mintmark.
