I know that one of these two Shih Kai Dollars is more common but the other is a triangle version and quite rare. Not sure on grades but hoping into MS. Possible faint circle in left hand quarter of ribbon in coin two but maybe just a shadow.
Triangle version also turns out to be 'Bold Leaves' and if you look at the stems of the grain wreath you can see a line of detail running through the centre of them, this is not present in the common varieties.
