A SAC star is born...
I found this error on a 2009 P SAC dollar from a bank roll. I don't collect errors unless it a true variety from NGC. I know this will be a one of a kind indeed. This can be seen with the naked eye as well.
The question I have how would the "star" get there and where would it have come from. It looks larger than the stars on the edge. Would this be considered a "Die Clash"? There are two parallel lines that are near this star as well but does not show up on the picture below.
Enjoy your weekend!
