Our online catalog includes unusual natural-history specimens and historically significant maritime collectibles, subject to availability.
From a Columbian mammoth molar to an ingot associated with the 1622 Nuestra Señora de Atocha shipwreck, these objects offer a tangible connection to the past.
Browse the available items below and explore our guide to fossil identification, shipwreck provenance, authenticity, preservation, and collecting.
Historic Shipwreck Treasure
Discover artifacts associated with historic maritime voyages, including precious-metal objects recovered from documented wrecks.
Understand why documented recovery history and chain of ownership matter.
Collecting Fossils & Historic Shipwreck Artifacts
Fossils and shipwreck treasures offer different ways to experience history. Fossils preserve evidence of ancient life, while shipwreck artifacts connect collectors with human exploration, trade, and maritime disasters.
Both collecting specialties place considerable importance on authenticity, provenance, condition, and documentation.
The most desirable specimens are often those whose identity and history can be supported by reliable evidence.
Prehistoric Fossils: Evidence of Ancient Life
Fossils are preserved remains, impressions, or traces of organisms from the geological past.
They may include teeth, bones, shells, plant material, and other evidence of prehistoric life.
Fossil collecting combines paleontology, natural history, geology, and the appreciation of unusual physical specimens.
Prehistoric Mammal Fossils
Teeth and bones from mammoths, mastodons, and other extinct mammals are popular natural-history collectibles.
Marine Fossils
Fossilized shark teeth, shells, and other marine remains provide evidence of ancient ecosystems.
Plant Fossils
Preserved leaves, wood, and other botanical material document ancient plant life.
Trace Fossils
Tracks, burrows, and other preserved activity can reveal how extinct organisms behaved.
Columbian Mammoth Fossils
The Columbian mammoth (Mammuthus columbi) was a large, extinct relative of modern elephants.
It inhabited parts of North America during the Pleistocene epoch. Its fossils are associated with prehistoric environments that differed significantly from those of today.
Why Mammoth Molars Are Distinctive
Mammoth molars contain multiple enamel plates adapted for grinding vegetation.
Their distinctive structure helps paleontologists study mammoth anatomy, feeding habits, and evolutionary relationships.
Columbian Mammoth Upper Molar Set
IDC's catalog includes a Columbian Mammoth Upper Molar Set described as recovered from Florida's Peace River in the Sarasota region.
The Peace River is well known among fossil enthusiasts for prehistoric vertebrate remains.
Collectors should review the individual specimen's condition, completeness, restoration disclosures, and available recovery history.
Florida's Peace River & Fossil History
Florida has a rich prehistoric record, including fossils associated with ancient marine environments and large terrestrial mammals.
Rivers and sediment deposits can expose fossils that were preserved long before modern Florida's landscapes developed.
The Peace River is especially familiar to collectors of fossil shark teeth and prehistoric mammal remains.
Fossil recovery may be regulated according to location, ownership, specimen type, and applicable laws.
Important:
Florida fossil collecting
can require permits,
and collecting rules
differ for state-owned
lands, waterways,
private property,
and protected areas.
Confirm lawful recovery
and ownership before
purchasing or collecting.
Historic Shipwreck Treasure
Historic shipwrecks provide evidence of maritime trade, exploration, transportation, and international commerce.
Recovered artifacts may include coins, silver ingots, gold objects, navigational equipment, ceramics, and other cargo.
Shipwreck artifacts are valued for more than their material composition.
Their historical associations, recovery documentation, condition, and legal provenance may contribute substantially to collector interest.
The 1622 Nuestra Señora de Atocha Shipwreck
The Spanish galleon Nuestra Señora de Atocha sank during a hurricane in September 1622 near the Florida Keys.
The vessel was part of Spain's Tierra Firme fleet and carried valuable cargo associated with Spanish colonial trade.
The wreck became internationally famous following the discovery of its principal treasure deposit in 1985.
Artifacts associated with the Atocha include silver bars, coins, gold objects, and other historical materials.
Why Atocha Treasure Is Collectible
Atocha artifacts connect collectors with seventeenth-century maritime history, colonial precious-metal production, and archaeological recovery.
Their appeal depends heavily on reliable attribution to the shipwreck and documented chain of ownership.
IDC's Atocha Shipwreck Silver Ingot
IDC lists a 1622 Nuestra Señora de Atocha Shipwreck Ingot, 603/1400.
The product description includes certificate information attributing recovery to Treasure Salvors, Inc.
The listing identifies a stated Ley fineness number of 2380/2400, a Grade 1 designation, and reference 0603/1400.
These details can help collectors investigate the ingot's attribution, historical context, and supporting documentation.

Authentication note:

Understanding Spanish Colonial Silver Ingots
Silver ingots transported aboard Spanish colonial vessels may bear markings associated with production, assaying, taxation, and shipment.
Such marks can help researchers investigate how silver was produced, recorded, and transported during the colonial period.
Assayer Marks
Marks associated with examination of precious-metal content.
Fineness Marks
Numerical markings indicating a stated silver purity under a historical measurement system.
Tax Marks
Stamps associated with colonial revenue and taxation procedures.
Inventory Identifiers
Numbers and markings that may assist with historical recordkeeping and attribution.
Interpretations of individual marks should be supported by qualified research and documentation specific to the artifact.
How to Authenticate Fossils & Shipwreck Artifacts
| Consideration | Fossils | Shipwreck Artifacts |
|---|---|---|
| Identification | Species or specimen attribution | Artifact type and historical attribution |
| Provenance | Documented collection location and ownership | Recovery records and ownership history |
| Condition | Completeness, fractures, repairs, restoration | Corrosion, conservation, damage, alterations |
| Documentation | Collection records, specialist reports | Certificates, recovery records, identifiers |
| Legal Status | Lawful collection and transfer | Lawful recovery, ownership, and transfer |
Certificates should be assessed according to the credibility of the issuer and the evidence supporting the claim.
Some fossils contain repaired or reconstructed sections, while some shipwreck artifacts require conservation to stabilize their condition.
Those treatments should be disclosed when relevant to a purchase.
What Determines the Value of Fossils & Shipwreck Treasure?
Rarity & Historical Interest
Scarcity, significance, and collector demand influence desirability.
Authenticity & Provenance
Reliable documentation can be especially important for valuable artifacts.
Condition & Preservation
Completeness, repairs, conservation, and physical stability can affect value.
Market Comparables
Recent sales of genuinely comparable specimens help establish market context.
A shipwreck silver ingot may command a premium beyond the intrinsic value of its silver.
Similarly, a fossil's collectible value is generally determined by scientific interest, rarity, quality, and demand rather than precious-metal content.
How to Buy Fossils & Shipwreck Treasure Online
Before purchasing an artifact, review the item's exact description and photographs.
For fossils, confirm the identification, dimensions, completeness, restoration, and known origin.
For shipwreck artifacts, investigate the claimed wreck, recovery documentation, legal ownership, and available certificates.
Consider whether specialist examination is appropriate before a significant purchase.
Review applicable shipping restrictions and import/export requirements, particularly for internationally sourced fossils and archaeological objects.
How to Preserve Historic Artifacts
Fossils and recovered maritime objects may require different storage and conservation conditions.
Protect fossils from unnecessary handling, impact, and unsuitable environmental conditions.
Historic marine artifacts can contain residual salts or corrosion products that require specialist conservation.
Avoid aggressive cleaning, polishing, chemical treatment, or restoration without qualified guidance.
Keep certificates, collection records, and other provenance documents together with the artifact's inventory information.
