The article by Matt Dickerson, "Bear Archery Kodiaks 1950-1966", states that some early '59s were built without coins. According to him, the 64" had two different sight window lengths, 6" for weights up to around 50# and 4" for heavier weights. Nothing I've seen in the pictures tells me this is not such a '59, but I don't even play a bow collector on TV, so that's JMHO.
