1917-S Philippines 50 Centavos: Authenticating the Rare ‘Broken 7’ Variety (Allen-14.06a Type 3)

Counterfeit Crisis: Safeguarding Your 1917-S ‘Broken 7’ Treasure

As colonial-era Philippine coins surge in numismatic value, one prize stands vulnerable: the 1917-S 50 Centavos ‘Broken 7′ variety. This silver beauty’s rising collectibility has made it a counterfeiters’ favorite target. With three distinctive sub-varieties (Types 1-3) and subtle diagnostics separating authentic pieces from fakes, even veteran collectors can be fooled. Let’s transform you into a authentication expert through weight analysis, metal composition tests, and die marker mastery – your essential toolkit for navigating today’s treacherous market.

The ‘Broken 7’: A Mint Error With Historical Soul

Born at the San Francisco Mint during WWI’s final days, these 75% silver coins capture a pivotal moment in Philippine-American history. The captivating ‘Broken 7’ (Allen-14.06a) emerged from a mint worker’s errant hammer blow during die preparation. As veteran collector Roy Martinez observed in our forum:

“That fractured upper right corner on the 7? Pure poetry in metal! It’s either a double-punched digit, a shifted punch, or a damaged tool – frozen in time when the planchet met the die.”

Three distinct error manifestations create collecting thrill:

• Type 1: Split top like a lightning bolt
• Type 2: Point protrusion like a tiny metal spear
• Type 3: Both features dancing together (the star shown in our forum image)

Authenticating Your Treasure: The Collector’s Toolkit

The Weight of Truth

Every genuine ‘Broken 7’ cradles exactly 10.00 grams of history (±0.10g). Modern fakes stumble here because:

• Base metals lack silver’s heft
• Cast counterfeits develop porous, lightweight bodies
• Electrotypes stack uneven layers like stale pastry

Magnetism Never Lies

True specimens contain only non-magnetic silver and copper. Wield a neodymium magnet:

• Pure silver song: No attraction
• Fake’s tell: Even slight pull reveals iron’s dirty secret
• Beware: Some sophisticated fakes now mimic non-magnetic composition

Measurements Matter

Compare against these mint-condition standards:

• Diameter: 27.00mm (±0.15mm) – a silver dollar’s perfect sibling
• Thickness: 2.00mm at edge (±0.10mm) – no pancake-flat pretenders

Type 3 Diagnostics: The Naked Truth Under Glass

Our forum image reveals Type 3’s two signature features – the holy grail for authentication:

1. The Fractured Digit
Under 10x magnification, spot the 0.3-0.5mm vertical split at the 7’s crown. This frozen moment captures a misaligned date punch striking at an angle, leaving a tiny crevice that shouts authenticity.

2. The Protrusion Perfection
A microscopic metal extrusion (0.1-0.2mm) juts southwest from the 7’s foot – like a miniature silver peninsula. This forms when the date punch rebounded during its second strike, pushing metal beyond the original boundary.

Secondary Markers of Merit

• Obverse: Seek the delicate die crack bridge between stars 4-5
• Reverse: Verify triangular tail feather alignment on the eagle
• Edge: Count 98-100 sharp reeds – no lazy flat spots allowed

Fake Spotting: Three Counterfeit Flavors

1. Cast Chinese Imposters

• Surface texture: Orange peel skin under magnification
• Weight failure: Typically 9.2-9.5g – featherlight fakes
• Edge betrayal: Reeding resembles worn saw teeth

2. Electrotype Doubles

• Edge seam: Like a poorly welded tin can
• Sound test: Thuds instead of silver’s crystalline ring
• Weight gain: 1-2% heavier from adhesive layers

3. Altered Date Frauds

• Micro-tooling: Scars in date fields under 30x light
• Font crimes: Numbers spaced like strangers on a bus
• Missing artistry: No trace of original die polish lines

The Professional’s Authentication Playbook

Deploy this battlefield-tested protocol:

Stage 1: The Eye Exam

• 10x loupe inspection of date/mintmark
• Die marker verification – no compromises
• Patina assessment: Natural toning vs. chemical baths

Stage 2: Metrology Lab

• Precision weighing to 0.01g sensitivity
• Digital calipers dancing across diameter
• Specific gravity test (true silver sings 10.31)

Stage 3: Nuclear Option

• XRF gun: Metal composition in seconds
• Electrostatic tests to expose cast fakes
• 3D profilometry mapping surface like a topo chart

Market Realities: Valuation With Vision

Genuine Type 3 specimens command fierce premiums based on eye appeal and preservation:

• VG-8: $150-$200 (character-filled warriors)
• F-12: $300-$400 (collectible starters)
• VF-20: $600-$800 (detail-rich sweet spot)
• AU-50: $1,200-$1,600 (lustrous tempters)
• MS-63: $3,000+ (museum-grade dreams)

PCGS/NGC slabs add 20-30% premiums – not just for authentication, but for showcasing superior strike quality and original surfaces that make collectors’ hearts race.

The 1917-S ‘Broken 7’ Type 3 represents everything we love about numismatics – history frozen in silver, minting drama, and the thrill of the hunt. Its dual nature as a rare variety and precious metal artifact makes it perpetually desirable. Master these authentication techniques: weight thresholds that separate truth from lies, magnetic responses that sing of silver purity, and die markers that whisper minting secrets. In today’s market flooded with fakes, this knowledge protects both your passion and your pocketbook.
