Overview

A crudely struck, thick silver cob coin encased or photographed within a textured bezel or protective holder, showing a cross on one side and a shield on the other.

Historical significance

Cobs were hand-struck rough silver coins produced in the Spanish American mints from the early 16th century until 1732. They were widely used as currency throughout the global trade networks of the Spanish Empire and are famously associated with pirate treasure and shipwrecks.

Obverse (front)

Displays the characteristic Hapsburg shield showing the arms of Castile and León, surrounded by remnants of Latin legend.

Reverse (back)

Features the Jerusalem cross (or potent cross) with quadrants containing castles and lions, typical of Spanish colonial cob coinage.

Estimated value

$50 - $300+ depending on the clarity of mint marks, assayer initials, date, and overall completeness of the strike.

What drives this coin's value

Completeness of the cross and shield, presence of a visible date and mint mark, assayer initials, overall centering, and shipwreck pedigree.

Grade assessment

About G to VG (Good to Very Good) details, heavily clipped and crudely struck as typical for cobs, with wear on the high points.

Mintage & rarity

Scarce to rare depending on the specific assayer, king, and year, though many recovered from shipwrecks are available to collectors.

Authenticity & counterfeit red flags

Check for correct silver density and weight, genuine hand-struck fabric (uneven pressure, thick irregular edges), and watch out for modern cast replicas or fantasy pieces often sold as pirate treasure.

Notable varieties & errors

Overdates, rare assayer combinations, and distinct mint variations from Mexico City, Potosi, Lima, or Cartagena.

Care & preservation

Store in a stable environment with low humidity in an inert, PVC-free coin flip or capsule. Do not clean, polish, or wash the coin, as this significantly reduces its numismatic value.
