  • Portrait of Pope Gregory XIII.
  • Inscription: "GREGORIVS XIII PONT" (Gregory XIII, Pontiff).

  • Medal alone: about 3 cm diameter.
• Weight: About 1 ounce with handle.

Historical Context

• Pope Gregory XIII (1572–1585) is best remembered for commissioning the Gregorian Calendar (which replaced the Julian calendar).
• Medal Origin:
  • These medals were originally created in the late 16th century as religious gifts, often distributed during jubilees or important religious celebrations.
  • The medal later being repurposed into a spoon (likely during the 18th century) follows a common practicefor religious souvenirs for christenings or baptismal gifts.
• S. GIAM is likely a later silversmith’s signature, but identifying the exact workshop would need deeper archival research or a specialist in Italian silver.

Condition

• Good.
  • Medal details still discernible, although some rubbing and wear is visible, consistent with age.
  • Handle and attached medal appear solid, no obvious signs of major repair.
  • Surface tarnish appropriate for antique silver — should not be over-cleaned as patina adds value.

Estimated Current Value

Based on:

• The rarity of authentic Papal medals from the 1570s,
• The decorative silverwork (religious spoons are collectible),
• The condition and completeness,
• Comparable museum examples (such as the one you mentioned at Stanford, and also auction house sales of similar Papal silver items),

A reasonable auction estimate would be:

$800 to $1,500 USD, possibly higher if marketed well to religious artifact collectors, numismatists (coin collectors), or fine antique silver buyers.

Private sale retail value (especially through a religious antiquities dealer) could push closer to:

$1,500 to $2,000+ USD.
