I hammered home this beautiful Egyptian imitation of an Athenian tetradrachm today at the CNG keystone auction. The surfaces are not the best, but it still has a very pleasing style, toning and centering. EGYPT, Pharaonic Kingdom. Uncertain pharaoh(s). Late 5th–mid 4th centuries BC. AR Tetradrachm (24mm, 17.03 g, 9h). Imitating Athens. Obverse: Helmeted head of Athena right, with frontal eye. Reverse: Owl standing right, head facing; olive sprig and crescent to left; all within incuse square. References: Van Alfen, Mechanisms, Group III.A.1, Fig. 1 = Buttrey Type B. Provenance: From the Robert W. Bartlett Bequest Sold for the Benefit of the American Numismatic Society. Ex Ponterio 18 (26 March 1985), lot 226.
