XVI / XVII - England - Token / Seal? Great Britain Coat Of Arms

The inscription is of course the motto of the Order of the Garter, and the arms are those of the Kingdom of England. Equally however, this is certainly not an impression of the Great Seal of England, as those always had a representation of the monarch enthroned, with his or her titles, and the reverse or counterseal was usually the monarch on horseback. Nor, so far as I can tell, could it be the seal of the Order of the Garter, which appears to be something quite different, with an equestrian figure. In any case the Garter is almost always depicted encircling the plain Cross of St George, not the Royal Arms.
