Spanish Colonial cob coins are among the most misunderstood and aggressively misrepresented coins in the global numismatic market. Their irregular shapes, uneven strikes, and crude appearance often create false confidence—allowing cast fakes, altered originals, and chemically aged replicas to pass casual inspection.
This system replaces surface-level assumptions with a professional authentication and ownership framework built specifically for Spanish Colonial cob coins. The guides focus on hammered strike behavior versus cast fabrication, edge seams and mold lines, filing and adjustment marks, and the detection of artificial patina, acid etching, and chemical aging—critical diagnostics where genuine cobs reliably separate from modern fabrications.
The bundle also addresses attribution and long-term ownership considerations, explaining how minting method, metal behavior, surface integrity, and historical context affect authenticity confidence, market liquidity, resale positioning, and value durability in the cob-coin market.
This framework should be used before purchasing, consigning, reselling, or insuring any Spanish Colonial cob coin, particularly in shipwreck-adjacent claims, private sales, online marketplaces, or estate contexts where provenance narratives often exceed the supporting evidence.

Real vs. Fake: Spanish Colonial Cob Coins Cast vs Hammered Strike Diagnostics
