Scientific Verification & Condition Report:
The coin is in an outstanding XF (Extremely Fine) condition for the issue. It features exceptionally sharp Gothic inscriptions, full volume on the central crowns and fleurs-de-lis, and is covered by a beautiful, deep historic cabinet patina. At the 7 o'clock position (on the reverse), there is an authentic, contemporary flan crack created during the medieval hand-hammering process. This is completely standard for the era and serves as an additional guarantee of origin.

Absolute authenticity and historical pedigree are scientifically verified by a professional XRF (X-ray fluorescence) spectrometry analysis. The metallurgical report officially confirms a precise composition of 46.33% Silver (Ag), perfectly matching the official royal minting standard for the 1420 billon issue, entirely eliminating any possibility of modern reproductions.
