Great coin. I was too late, but I would have said 65. I also love the golden color these things seem to take on. My first Liberty nickel (which I no longer own) was a similar-colored NGC MS64 1911.
Rusty, I think the Eschenbach is worth it. It's a 3+6 Achromat with virtually no distortion out to the edge of the lens. Very lightweight too.
I've had a 10x for about twenty five years and love it. If I remember correctly, I paid about seventy bucks for it. Seemed very expensive at the time, but it was well worth it in the long run.
