| Reverse description | The reverse of this control trial piece presents a series of concentric circular grooves covering the entire face of the planchet, a characteristic feature of Monnaie de Paris épreuves de contrôle used to verify die alignment, planchet thickness, and striking pressure. The surface, struck in silver-plated lead, shows multiple raised concentric rings radiating from a central boss, with no inscriptions, legends, or figurative design elements present. This type of reverse is standard for internal mint quality-control specimens and is not intended for circulation. |

| Additional information |
Épreuves de contrôle are internal Monnaie de Paris test strikes used to verify die alignment, field quality, and hub transfer before a production run is approved. They were never intended for sale or distribution. This particular piece — struck in silver-plated lead rather than the silver of the circulation issue — allowed technicians to assess surface definition without consuming precious metal blanks. Lead's malleability also reveals die imperfections that harder alloys can obscure.
