I am at 64. Using SLEC which was recently brought up in another thread figure I would try it here. Strike - 64 x 0.2 = 12.8 Luster - 65 x 0.2 = 13 Eye Appeal - 65 x 0.2 = 13 Contact Marks - 64 x 0.4 = 25.6 Overall - 64.4
Well, we have our answer from the slab photo. The luster in not great. Strike is fine, surfaces clean, but it is luster deprived.
Possibly, but given the other things on the coin are fine, it is most likely luster. Especially since the strike is medium to good for that date, I suspect luster. Probably overdipped and retoning.
