I would grade it as VF with a shot at XF. Color looks a bit dull so it could be cleaned, or it could just be my crappy 'puter.
I am at work and do not have my book or notes so off the top of my head...
.500 silver
Fourth obverse ( they had problems striking and with metal flow and changed the details and relief trying to get it to work.) and I think this is the 'new' lion on crown reverse.
Now watch someone with real knowledge come along to tell me I am all wet.
Hope it helped.
