For collectors, numismatists & alternative-asset investors
The collector's field guide to Spanish gold coins
From a $300 cob escudo to a $50k royal doubloon, the gap between a great buy and a costly mistake usually comes down to three things: mint mark, grade, and provenance.

What you'll find here
Everything the auction catalog doesn't explain
Whether you're attributing your first cob or tracking down a legitimate shipwreck COA, this is the reference desk a knowledgeable collector friend would hand you.
Authentication & Grading
A shipwreck coin with a broken COA chain is worth a fraction of one with clean provenance — reviewers and veteran collectors consistently flag this as the single most expensive lesson in the hobby. Here you'll learn to read slab certifications, spot red flags in counterfeit cobs, and understand what 'galano' (an unusually well-struck cob) actually means for market price.

Storage & Collecting Supplies
The right capsule for a raw cob isn't the right capsule for a PCGS-slabbed 8 escudo, and archival storage matters more than most new collectors expect. We review magnifiers, display cases, reference books, and secure storage solutions so your collection stays protected and properly presented.
