This listing includes an authentic Spanish maravedí from the 17th century, mounted in a protective capsule attached to a double-sided display card approximately the size of a standard postcard. The card features historical artwork and information about the role these coins played during the age of Spanish exploration and Caribbean piracy.

This coin was struck in Spain during the reign of King Philip IV and dates to 1621–1665 AD. It belongs to the popular "castle-and-lions" type, one of the most recognizable designs of Spanish copper coinage of the seventeenth century, named after the heraldic castles and lions that appear on these historic coins.

Maravedís were widely used throughout the Spanish Empire, including in ports, colonial settlements, and trading centers connected with Spain's Caribbean possessions during the Golden Age of Piracy. Coins of this type belonged to the monetary world of sailors, merchants, adventurers, and pirates who traveled and traded between Spain and the New World.

The two-sided collector card transforms the coin into a small historical display piece, making it an excellent gift for fans of pirate history, maritime adventures, and beginning collectors.

This particular example is extremely worn from centuries of circulation, with most of the original detail no longer visible.
