Or the coin as an example of the small date. Photos of full coin would be nice to see, and a close up of Liberty too.
I was looking more at the point of the 9. The seven does look low. Small mintmark matches better. I will hold out for liberty.
The mintmark was hand-punched into the die prior to 1990 so it can't be a doubled die. Like the date, it is machine doubling. ~ Chris
