Crafting Peruvian Pillars: A Coin Ring Artisan’s Guide to 1751-1772 Lima Real Coins

Historical Significance

Before diving into crafting possibilities, it’s worth understanding what makes these Peruvian pillar coins so special. Minted in Lima between 1751-1772, these .917 fine silver coins represent a fascinating chapter in Spanish colonial history. Their distinctive crowned pillars and waves design, combined with the crowned shield of the Spanish monarchy, creates a visual narrative that’s simply unmatched in modern coinage.

Metal Composition and Durability

The .917 fine silver composition (91.7% silver, 8.3% copper) makes these coins exceptional candidates for jewelry crafting. This “coin silver” alloy strikes the perfect balance – the silver provides that coveted luster and workability, while the copper adds crucial hardness for everyday wear. Unlike pure .999 silver, this slightly harder alloy resists scratching and deformation, essential qualities when transforming a coin into a ring that must withstand daily use.

Design Details and Aesthetic Appeal

The pillar coinage’s iconic design truly shines when crafted into rings. The crowned pillars and waves on the obverse, along with the crowned shield reverse, create a continuous pattern that wraps elegantly around the band. The 1 real denomination (approximately 3.0-3.2 grams) hits that sweet spot – substantial enough to create a meaningful band while remaining comfortable for daily wear. At 1-2mm thick, these coins offer structural integrity without feeling cumbersome.

Notable Dates for Crafting

Based on collector insights, certain dates are more accessible for crafting projects:

• 1757 – Described as “common” and most readily available
• 1753-1757 – Considered relatively common, with potentially over 1,250 surviving specimens
• 1758 – Extremely scarce, with collectors reporting only 3 sightings in two years

Rarity Considerations

While 1757 is the go-to choice for crafters, the rarity spectrum is fascinating. Some dates are so scarce they’re essentially off-limits for crafting. As one collector noted, “The top rarest 1 reales from Peru 1751-1772 are the unique 1751 (impossible date really most do not count it in the set) – 1752 – 1760 Carolus – 1766 – 1767 – 1768 and 1772.” The extreme rarity of certain dates (1751 is unique, 1760 Carolus has only 12-15 known examples) makes them impractical for crafting – their historical significance and numismatic value far exceeds their worth as raw material.

Working Properties

The .917 silver alloy offers excellent working properties for coin ring crafting:

• Annealing Response: Responds beautifully to annealing, becoming more malleable when heated and cooled properly
• Formability: Can be folded and shaped without cracking – crucial for the coin ring process
• Polish Retention: Holds a high polish and develops a gorgeous patina over time

Authentication Considerations

Authentication is crucial when sourcing coins for crafting. The upcoming second edition of Brad Yonaka’s guide to these coins will be an invaluable resource for identifying genuine specimens and understanding the various varieties. Key authentication points include proper weight (approximately 3.0-3.2 grams for 1 real), correct silver content (.917 fine), accurate design details specific to the Lima mint, and appropriate wear patterns consistent with the coin’s age.

Ethical Considerations

As a coin ring artisan, I always weigh the historical significance of each piece. While common dates like 1757 are excellent candidates for crafting, extremely rare dates should be preserved for collectors and historians. The forum discussion reveals that even “common” dates from this series are becoming increasingly difficult to find, with some collectors reporting only seeing certain dates once every few years. The numismatic value of these coins, particularly rare varieties, often exceeds their worth as crafting material.

Conclusion

The Peruvian pillar coinage from 1751-1772 offers exceptional potential for coin ring crafting, particularly the more common dates like 1757. The .917 silver composition provides the perfect balance of beauty, durability, and workability. However, the extreme rarity of certain dates and the historical significance of these coins should always be considered before transforming them into jewelry. For crafters interested in working with these historical pieces, I recommend focusing on authenticated common dates, understanding the proper techniques for working with .917 silver, and always respecting the historical value of these fascinating colonial coins. The upcoming second edition of Brad Yonaka’s guide will be an essential resource for both collectors and crafters working with these remarkable pieces of history.
