Payment processor directory for bullion dealers
Published Nov 5, 2026
This is a starting list of well-known US payment processors and gateways, with links to their own sites. Bullion Price Check is not a partner, reseller or agent of any of them and earns nothing from these links. A listing is not an endorsement, and inclusion does not mean a processor accepts precious-metals merchants.
Important for bullion: many processors restrict or prohibit precious metals, bullion or "investment" goods in their terms, or require extra underwriting. Read each provider's restricted-business list and get written approval for your category before you take orders.
