50 Centimes

Guadeloupe's coinage was administered through the Établissements français de l'Océanie monetary framework, with locally-specific issues authorized separately from metropolitan France precisely because the colonies maintained distinct commercial ecosystems tied to sugar and rum economies rather than the franc zone proper. The 50 centimes type ran across nearly two decades with no mid-series design revision — unusual for a colonial issue spanning both the pre- and post-WWI periods.

All pieces were struck at the Paris Mint. Copper-nickel was chosen partly to resist the humidity and salt air that accelerated corrosion of bronze coinage throughout the French Antilles.
