Sources & References

We build on primary sources, not hype.

Our education and our AI guides, Aurelia and Sterling, draw on the most authoritative names in precious metals — global market bodies, government data, official mints, and investor-protection regulators. Here's the canon behind what we teach. Nothing here is investment, tax, or legal advice; always do your own diligence.

How we use these. We cite primary sources for data and definitions and never fabricate figures. Prices and market data change constantly — always verify current numbers at the source.
