From Moidores to Reales: Assessing Early American Coinage for Jewelry Crafting

Not Every Coin Rings True: When History Meets the Hammer

Every coin tells a story, but not every coin rings true beneath a jeweler’s hammer. In my two decades of transforming historical treasures into wearable art, I’ve learned colonial-era coins demand equal parts reverence and metallurgical know-how. Let’s explore three legendary pieces – the Brazilian 20,000 Reis, French Ecu, and diminutive Brazilian 400 Reis – through the eyes of both collector and craftsman.

History You Can Hold

These aren’t mere discs of metal – they’re time capsules of colonial commerce. The Brazilian 20,000 Reis (1725), a hefty 53.78g of shimmering 22K gold, powered empires. Meanwhile, the Brazilian 400 Reis at just 0.893g facilitated daily bread purchases. And the French Ecu? Its 41mm silver canvas dominated markets. Holding these is touching the very pulse of history.

Metal Matters: Composition & Craftability

Golden Giants

• Brazilian 20,000 Reis (1725): 91.6% pure gold sings beautifully under the torch but demands perfect annealing. That glorious luster? It’ll make your ring glow like colonial sunlight.
• Brazilian 400 Reis: A grain-sized challenge at 0.893g. Nearly translucent at 0.5mm thick, this micro-coin tests even master jewelers. Save these for specialists or preservation.

Silver Standouts

• French Ecu: 90-95% silver develops stunning patina but watch for copper’s temper. That beautiful grey toning? It’s history whispering through chemistry.
• Spanish 8 Reales: 27g of 90.3% silver often shows adjustment marks – not flaws, but stories etched in metal. Perfect for pieces celebrating authenticity.

Designs That Dance: Aesthetic Alchemy

The Brazilian 20,000 Reis

Portugal’s crowned shield springs to life when domed, casting dramatic shadows worthy of a king. That 29mm diameter creates substantial rings (size 10-12) with museum-worthy eye appeal. Every strike detail becomes a tactile delight.

The French Ecu

Regal portraits and heraldic grandeur unfold across 41mm of silver canvas – a storyteller’s dream. But those adjustment marks? I’ve turned colonial minting quirks into design features that whisper, “I survived three centuries.”

Brazilian 400 Reis

This tiny marvel breaks hearts. At 15mm, even loupes strain to reveal its simple cross design. I’ve set these in signet rings like diamonds – precious fragments of financial history best appreciated magnified.

The Collector’s Conundrum

“Paid $5,600/oz for an AU details 20,000 Reis with a test cut. Melting it would’ve been sacrilege.” – @oldabeintx

This collector’s agony echoes in every artisan’s workshop. When considering transformation, we always weigh:

• Does its numismatic value dwarf melt value?
• Do existing marks (test cuts, environmental wear) enhance character without ruining collectibility?
• Can we showcase its soul without erasing its provenance?

Mastering the Metal: Solutions From the Bench

Sizing Secrets

The Ecu’s grand 41mm span makes bold statement pieces, while micro-coins like the 400 Reis shine in bezel settings. My signature technique? Suspending tiny treasures in clear resin to preserve every detail.

Gold’s Memory

22K’s softness requires finesse. Through burned fingers and ruined blanks, I perfected a seven-stage annealing process that coaxes Brazilian gold into rings without losing its historic soul.

Patina Poetry

That Ecu’s silvery-grey blush? Centuries of sulfide conversation. My micro-abrasive technique preserves desirable toning while halting corrosion – letting history’s patina shine through.

Conclusion: Preservation or Transformation?

These colonial workhorses straddle worlds: bullion and artifact, commodity and cultural treasure. The 20,000 Reis’ gold begs for the torch, but its numismatic significance gives pause. Ecu specimens with adjustment marks become my passion – turning minting “flaws” into features. As for the 400 Reis? Its place as history’s smallest circulating gold coin argues fiercely for preservation.

Here’s my workshop creed: If a coin sparks more historical debate than artistic vision, it belongs under glass. But when a piece bears the scars of circulation – test cuts, environmental wear, honest scratches – transforming it becomes an act of resurrection. We’re not destroying history; we’re giving it new life on the hands of those who cherish it most.
