Yes it is. The obverse is a full F15, with a reverse weaker. I think F12 was a fair grade. It's common on the well worn early dates to have a weaker reverse.
Newp for my type set. Holy crap these things are small! Not only small in diameter, but they are super thin.
Still amazing to me what a great job my iPhone does capturing toners. This was shot in indirect sunlight underneath two skylights in my living room.
I guess there is a very fine line(s), literally and figuratively, between F-15 and VF-20. I love the surfaces on this one. Premium for those of us that love mid-grade circulated.
