France
Henri V Pretender bronze Essai 5 Francs 1873 UNC, Maz-927B (R2), VG-2736. 43mm. 32.59gm. A much lesser-seen type than Henri's more prolific "young bust" essais of the earlier 1830s, toned to a wonderfully glossy mahogany with specimen-like surfaces and the faint remnants of die rust visible around the legends.
