Variety question, 1951-D RPM
So I don't usually post about varieties but my father recently came across this cent- to me it looks like RPM-001.
What do you think? Is this as tough to find as the pop report and price guide suggest? I am not sure what the "value" of something like this would be but it seems like it might be worth it to get into PCGS plastic, I am just not sure.
This picture is pretty much all I have to go off of, but I think it shows it well enough.
