50 Centésimos Obverse Trial

Panama's first national coinage was struck at the Philadelphia Mint under contract, following the republic's separation from Colombia in November 1903. The 1904 series was conceived and produced with remarkable speed given the country was barely months old. Trial pieces in copper served as press and die tests before the silver production runs were authorized, allowing mint technicians to confirm relief depth and die alignment without committing precious metal.

Philadelphia struck the copper trials for internal use; very few left the mint through official channels.
