The detail behind the facts

The core rule

Photos, receipts, certificates and registration emails together prove provenance.

Collectors who skip this step usually discover the problem the hard way — a faded shoulder, a pitted alloy base, or a certificate that no longer matches the listing.

Practical step

Buyers pay premiums for paper they can verify.

Most first-time buyers only feel the real constraint after the piece has sat in its box for a season — by then the easy window to decide has already closed.

How collectors apply this

Value follows scarcity, condition and demand — nothing else.
The cheapest protections are documentation and patience.

Common mistakes to avoid

Displaying within arm's reach of a south-facing window and calling the fading 'character'.
