Rare Spanish Shipwreck Pewter Screw-Top Bottle Cap (c. 1600s) – San Martín Wreck, 1618
This rare Spanish shipwreck artifact is a pewter screw-top bottle cap dating to the early 1600s, recovered from the wreck site of the Spanish ship San Martín, which sank off the coast of Florida in 1618 during the Golden Age of Piracy.
An early example of screw-top bottle technology, pieces like this represent a short-lived innovation in sealing containers. While the concept was ahead of its time, it proved impractical and was quickly abandoned—making surviving examples especially scarce today.
Recovered from the historic wreck site, this artifact bears the marks of centuries beneath the sea, with natural patina and surface wear that speak to its long submersion and age. Its connection to a documented shipwreck adds significant historical value and collectibility.
Professionally displayed in a protective case, this piece is a standout addition for collectors of shipwreck artifacts, early maritime technology, or Golden Age of Piracy relics.
