France
Louis Philippe I Error 5 Francs ND (1832-1848) F15 NGC, cf. KM749.1 (for type). Reverse struck through capped die. An already very rare mint error, made all the more so by the nature of obverse brockage, itself preserving the portrait of the July Monarch in a comparatively high and refined level of detail.
