50 Centimes - Yusuf Piedfort Essai, 5g Al-Br

Piedforts — struck at double or greater thickness on standard dies — were produced by the Paris Mint as presentation pieces for official approval and archival purposes, not for circulation. Morocco's 1925 coinage was issued under the French Protectorate, and essai strikes like this one were part of the formal submission process by which the Monnaie de Paris documented proposed types before authorizing production runs.

Lec#206f places this among a small documented series of aluminium bronze trial variants. The aluminium bronze alloy itself was relatively new to French colonial coinage in this period, having been adopted partly for its resistance to corrosion in North African climates.
