01 · Resumen ejecutivo
El fraude no está en el metal — está en la contraparte.
El oro es de los pocos activos que significan lo que dicen. Una barra Good Delivery emitida por LBMA en una bóveda auditada es el mismo instrumento desde hace un siglo. Por tanto, el fraude casi nunca es el metal en sí, sino las personas, sitios y custodios intermediarios.
Este briefing mapea las tipologías recurrentes, la cadena de detección, los reguladores que consultar y la secuencia institucional que aplica Ambank. Es un recurso de prevención de fraudes, no un consejo de inversión.
02 · Magnitud del problema
Tres números para memorizar antes de comprar.
Fraude de phishing 2024
USD 10m
USD 10m perdidos por 1,200 inversores en sitios falsos que ofrecían oro por debajo del spot.
Incautación de 2022
USD 50m
Falsificaciones con tungsteno incautadas por Interpol. Los compradores sufrieron un 30% de pérdida en el ensayo.
Refinerías acreditadas
< 100
Hay menos de 100 refinerías acreditadas en la lista LBMA Good Delivery en el mundo. El resto exige alta diligencia.
03 · Tipología de fraude
Seis patrones recurrentes en el fraude minorista.
La mayoría de las pérdidas reportadas se concentran en estas categorías ante el FBI IC3, la SEC y la FCA en años recientes.
- 1,200 investors, USD 10m, 2024
Spoofed dealer websites
Pixel-accurate clones of established retailers such as APMEX or JM Bullion, served from look-alike domains and surfaced via paid search ads. Buyers wire funds to mule accounts and never receive bullion.
- Interpol 2022: USD 50m seized
Counterfeit bars and coins
Tungsten- or lead-cored bars plated and stamped with high-purity hallmarks. Pass casual weight checks but fail acid, density and ultrasonic testing — losses of up to 30 percent on assay.
- Unregistered "custodians"
Gold IRA Ponzi schemes
Self-styled retirement custodians promising guaranteed 20 percent annual returns on physical-gold-backed IRAs. Funds rotate to pay early redeemers; storage, audit and custody are fictitious.
- Sell-side and buy-side
Non-delivery after payment
Sellers paid for metal that is never released from a third-party vault, or buyers who pay for shipments that never leave the origin country. Both versions exploit the gap between contract and physical handover.
- Door-to-door buy-back
Pressure-sold home pickups
Cold-called offers to buy household gold at wildly under-market prices, exploiting unfamiliarity with live spot. The figure quoted is often less than half of the legitimate scrap-gold benchmark.
- Allocated vs unallocated
Vault commingling fraud
Storage operators selling "allocated" accounts that are in fact unallocated pooled balances, with insufficient physical metal to cover all client claims. Discovered only when too many holders demand delivery at once.
04 · Detección de falsificaciones
Ocho pruebas, una respuesta institucional.
El problema es el tungsteno recubierto de oro. El tungsteno tiene casi la misma densidad del oro, burlando pruebas de peso. El plomo es más barato pero más detectable.
Las pruebas de campo no son concluyentes en barras. Sólo el ultrasonido, rayos X de fluorescencia y perforaciones destrutivas son confiables. La matriz debajo califica las técnicas.
Visual & weight check
FieldCompare hallmark, dimensions and weight against the manufacturer's published specification.DestructiveConclusiveDefeated by tungsten cores; acceptable only as a first filter, never as a basis for purchase.Magnet test
FieldReal gold is non-magnetic. Strong reaction to a rare-earth magnet rules out gold immediately.DestructiveConclusiveMany counterfeits use non-magnetic alloys, so passing the magnet test means very little.Ping / acoustic test
FieldReal gold rings with a long, high-pitched tone when tapped. Counterfeits tend to thud.DestructiveConclusiveUseful on coins, less reliable on bars and easily masked by surface plating.Specific gravity / density
Field or labGold density is 19.3 g/cm³. A water-displacement measurement quickly flags tungsten (19.25) and lead (11.34).DestructiveConclusiveTungsten cores match closely, so density alone is not decisive on bars.Acid scratch test
FieldStreak the bar or coin against a test stone and apply graduated nitric / aqua-regia acids.DestructiveConclusiveTests only the surface layer; tungsten-cored bars with deep gold plating can still pass.Ultrasonic thickness gauge
LabSound waves measure the speed of transmission through the bar; tungsten differs sharply from gold.DestructiveConclusiveDetects layered counterfeits without drilling; widely used by professional dealers.XRF spectrometry
LabX-ray fluorescence reads the elemental composition of the surface layer (typically 20–50 microns).DestructiveConclusivePowerful on coins; on bars must be combined with ultrasonic or drilling to see beyond the plating.Drilling assay
RefineryDrill a sample from the core, send to an accredited assayer for fire-assay or ICP-OES analysis.DestructiveConclusiveDefinitive. The standard arrival test for any institutional consignment.
05 · Reguladores y registros
Dónde verificar antes de enviar dinero.
London Bullion Market Association. Publishes the Good Delivery list of accredited refiners and vaults; the foundation reference for institutional bullion.
U.S. Financial Crimes Enforcement Network. Verify dealer registration as a Money Services Business or precious-metals dealer under the Bank Secrecy Act.
U.S. Securities and Exchange Commission. Use EDGAR to verify any filings; cross-check links to gold ETFs, mining stocks and IRA custodians.
U.K. Financial Conduct Authority. The FCA Register and the published warning list cover unauthorised firms and clones operating from the U.K.
Better Business Bureau. Useful as a secondary sentiment and dispute-resolution check; A or A+ is a baseline for U.S. retail dealers.
FBI Internet Crime Complaint Centre. Repeatedly publishes alerts on phishing dealer sites and gold-investment fraud; PSAs are good leading indicators.

07 · El costo real de propiedad
El precio spot es el inicio de la pila de costos.
El error común es creer que el spot es el precio final. Los costos reales abarcan la prima sobre spot, seguros, impuestos y almacenamiento.
El gráfico muestra las bandas comunes. Cualquier precio publicitado por debajo del margen inferior es engañoso o fraudulento.
Premium over spot
2 – 10%
0%typical max ~37%Dealer markup that funds minting, distribution and authenticity checks. Bulk bars trade at the low end; one-ounce sovereign coins at the high end.
Sales tax / VAT
0 – 20%+
0%typical max ~37%U.S. states range from 0 percent (Delaware, Oregon) to over 8 percent. UK investment-grade bullion is VAT-exempt; many EU jurisdictions levy standard VAT on coins and small bars.
Shipping & insurance
1 – 3%
0%typical max ~37%Bonded courier with all-risk cover for retail orders. Institutional consignments scale this down materially per ounce.
Storage (annual)
0.12 – 1.5%
0%typical max ~37%Allocated, audited vault accounts in London, USA and Singapore typically run at the low end. Retail home-delivered bullion incurs separate insurance riders.
Capital gains tax
0 – 37%
0%typical max ~37%U.S. long-term collectibles rate caps at 28 percent; short-term gains taxed as ordinary income up to 37 percent. UK CGT applies above the annual exemption; specific Britannia and Sovereign coins are CGT-exempt.
