How to buy coins safely online

Vet sellers, spot authenticity tests and protect your payment in any numismatic marketplace.

2026-05-24guíascomprasseguridad

The golden rule: verified trust

Before buying a coin of any real value, vet the seller. At Gold Silver Global every seller passes mandatory KYC; on other channels look for:

  • Profile age and public reputation.
  • Sales history with detailed reviews.
  • Availability to show the piece on a live video call.

Authenticity tests

A genuine coin passes all of these checks at once:

  1. Weight within ±0.1 g of the spec for bullion grade.
  2. Diameter measured with calipers, not by eye.
  3. Ring test is only a hint — modern fakes can defeat it.
  4. Magnetism: gold and silver are not ferromagnetic.
  5. Density via the Archimedes test confirms purity.

Protect your payment

  • Never use direct transfers (Bizum, IBAN) with strangers.
  • Use marketplaces with escrow — funds held until delivery is confirmed.
  • Demand insurance and tracked shipping.
  • Film the unboxing in a single take — it's the decisive evidence if something is off.

Bottom line

Buying coins remotely is safe when an intermediary validates the deal. Vet the seller, run physical checks, pay via a platform with escrow and document delivery.
