That would be a Dropped Letter or Number Too rare of an error to find. In the 36 years I've been searching and collecting I have never found one.
Wait... something is puzzling me here. When I did an overlay, I get this: The "O" in MONTICELLO is in front of his eyebrow, not behind his head. What am I missing?
I think your overlay is reversed because it has been turned horizontally instead of vertically, as in coin alignment
OMG!!! How could I have done that?! I'm supposed to be very good at Photoshop! Lol. Nevermind..... Sorry!
