The coin appears to be a slightly higher technical grade than attributed.  The surfaces are just slightly grubby however I can see more luster under the grunge than I would normally expect of a 53 coin.  Not worth cracking, conserving and resubmitting for me, but it might be for someone else as this is an example of Snow-8, a fairly scarce RPD.  Very tough to get a good image of the feature between the location of the repunching, and the surfaces, however I have done my best and will guarantee the attribution.
