| 背面描述 | The reverse presents the celebrated Hercules group composition designed by Augustin Dupré. The heroic nude figure of Hercules, wearing the leontè (lion's skin) over his shoulder, stands frontally at center, serving as the unifying force between the allegorical figures of Liberté on the left, who holds a pike surmounted by a Phrygian cap, and Égalité on the right, who bears the mason's level as her attribute. The Republican motto 'LIBERTÉ ÉGALITÉ FRATERNITÉ' is inscribed in the surrounding legend, and the engraver's name 'Dupré' appears in the field. |

The "épreuve de contrôle" is a specific category of French mint artifact — a lead striking used internally by the Monnaie de Paris to verify die alignment, depth, and relief before committing to production runs in silver or other final metals. These are not trial pieces in the commemorative sense; they are working documents, produced in lead precisely because its softness captures die detail under lower pressure and reveals flaws that harder alloys might mask.
The GEM references 159.1 and 159.2 suggest two die states or striking variants were formally catalogued, which is unusual and implies documented die progression at the control stage.
