Eagle Symbol on Gold or Silver
The best-known eagle mark is the French eagle's head (tête d'aigle), struck on French 18K gold since 1838. It is a guarantee mark applied by the French assay system, so even small French gold items carry the tiny eagle head rather than a '750' number.
Other eagle marks exist: Mexican silver carries a spread eagle in some mid-century marking schemes, German and Austrian systems used eagle devices in certain periods, and eagles feature in many maker's logos. As always, the shape, direction, and companions of the mark identify the system.

Frequently asked questions
Is French gold always marked with an eagle instead of 750?
French-assayed 18K gold typically carries the eagle's head guarantee mark; export and modern pieces may also show 750. The eagle's head itself certifies at least 18K under the French system.
