Yesterday, I posted a penny about an elevated rim which would be considered ridge rim.http://www.error-ref.com/?s=ridge+ring+
Now, I have this penny in question, I see it has a ridge rim.
But, I see doubling on the date, it looks like the 8 is a double.
I am assuming it can't be a double die (could be wrong) because the doubling is made in the die. I haven't seen it on the books.
I am thinking it is a Machine Doubling
some how related to the ridge rim.
Also note how there is a die break underneath on the inside of the D mint mark.
What do you guys think ?
