Can you find the markers? http://www.coppercoins.com/lincoln/diestate.php?date=1987&die_id=1987d1mm003&die_state=mds
Your photos are just a bit out of focus or a bit too far to see the markers. But it looks very promising. That is one of my particular RPM favorites! I hope it is.
Still a little out of focus but I think you have one. The condition of your coin looks good too! I hope I’m right; with coin in hand I’m sure you are feeling more confident. How did you come about it?
