thanks DCH. I figured it was KM63 but the picture doesn't look anything like the coin (at least not to me). I'm looking at the examples on the link you sent (I"ll need to study them more at home) but they look different not only from each other but from the picture for KM63. Can I assume that these 'variations' are all authentic KM63 varieties? Or maybe I just need to study the pictures more.
As far as grade and value, I agree it is a tough call with that photo but I was more interested to get an opinion on authenticity.
