I found this 1956D after seeing the variety vista I think it a rpm 16 but I know that it has to be exactly like it.....so I'm getting another opinion... It's hard to see the die scratches on the lapel in the photos...... View attachment 1500031 View attachment 1500031
Pictures are too fuzzy but I don’t see it. Here’s a link: http://coppercoins.com/lincoln/diestate.php?date=1956&die_id=1956d1mm002&die_state=mds
RPM 16 looks rotated clockwise. Yours doesn't chow the same look. The position looks close though. Better photos might help.
