The gold piece is the one I mentioned. The bust is of the same general shape, but not comical unlike yours. The reverse is completely different as you can see, with no MR divided by the shield. The legend is also different to the dated gold piece. The portrait on the 1st widowhood testoon is superb and superior to the efforts of the English engravers of the time. Copies or replica coins are often made by casting, with the raised line being the point where the two faces came together. You will probably find the remains of the casting sprue if you look carefully.
