Leo I — Gold Solidus, Constantinople (457–474 Ad) – 4.46 G – Certificate Of Authenticity

Superb imperial gold solidus struck in Constantinople under Emperor Leo I.
Obverse: the legend D N LEO PERPET AVG frames a helmeted and cuirassed military bust, seen three-quarters facing right, holding a spear and shield — finely detailed engraving, perfectly defined rows of pearls on the helmet, and sharply modeled facial and armor features.
Reverse: VICTORIA AVGGG Γ — Victory standing left, holding a long gemmed cross, with a star in the right field; in the exergue, CONOB, guaranteeing the mint authority and purity (obryzum) of Constantinopolitan gold.
The coin displays a warm, even luster, clean fields, and strong, well-centered reliefs characteristic of official Byzantine minting at its finest.
