Editorial standards & methodology

We aim to be useful and honest, and to be clear about what we know and what we don't.

Independence

Our editorial coverage is independent of any commercial relationship. Sponsored or affiliate content, where present, is clearly labelled.

Market data

Any index, movers or price figures shown are illustrative editorial references to convey direction, not live market quotes or valuations. Always verify against real sold prices and auction results before buying or selling.

Authentication

Our authentication guidance is general education. For anything of value, use a reputable third-party grading or authentication service.

Review

Guides are reviewed for accuracy before publication and updated when the market moves.
