There are some gold and silver coins exactly similar to those of Edward
IV., but bearing as mint marks a boar’s head, a rose-en-soleil, or
a rose-en-soleil on one side and boar’s head on the other, that are
conjectured to have been issued by this youthful king by authority and
order of his uncle the “Protector,” afterwards Richard III., whose
badges they bear. They are extremely rare.
