Shipwreck coins and artifacts—Spanish colonial cobs, milled reales, Portuguese gold, mixed colonial coinage, emeralds, silver bars, gold bars, navigational tools, and personal relics—rank among the most historically significant and highly forged items in the numismatic and maritime-collectibles world. Because authentic shipwreck material reflects centuries of saltwater exposure, natural corrosion, and period minting techniques, modern fakes often fail under structured visual analysis.
DJR Expert Guide Series, Vol. 510 provides the full non-destructive workflow for authenticating shipwreck coins and artifacts safely and professionally. This guide explains how to identify genuine corrosion behavior, differentiate struck coins from cast forgeries, evaluate encrustations, assess mint marks and assayer marks, analyze artifact construction, and detect modern artificial aging methods used to simulate shipwreck recovery.
Inside this guide, you’ll learn how experts:
Identify major shipwreck coin types including Spanish cobs, reales, escudos, and foreign trade issues
Evaluate authentic saltwater corrosion patterns and metal behavior
Distinguish struck coins from cast counterfeits using detail, edges, and relief structure
Recognize artificial aging methods such as acid pitting, heat darkening, and applied crust
Analyze encrustations for natural vs. synthetic mineral accretion
Assess shipwreck artifacts including iron tools, jewelry, musket parts, buckles, and ingots
Interpret mint marks, assayer marks, and period die characteristics
Identify fantasy pieces, incorrect marks, and style inconsistencies
Review provenance, certificates, salvage records, and recovery documentation
Apply a structured non-destructive authentication workflow from start to finish
Whether evaluating a piece of eight, a gold escudo, an encrusted artifact, or mixed shipwreck material, this guide equips collectors and appraisers with the complete methodology needed to distinguish genuine shipwreck items from reproductions or artificially aged forgeries.
