KM-148 variety, Philip V type.  Struck at the Mexico City mint.

A fantastic, original and well pedigreed piece with choice surfaces, rich golden orange color and lovely old rose and blue toning at the obverse rim which proved to be quite challenging to image without also getting a lot of glare from the slab as seen in this pic:

But all of that superb color is very evident in hand.

Ex Christie’s May 1985 sale of the Norweb Collection, lot #8.
