Useful records, honest uncertainty.

Identity and specifications

Maker, form, weight, purity, origin, era, and series are checked against mint documentation, museum or government references, established refinery histories, and reputable bullion catalogs. Similar names do not automatically mean identical products; weights, marks, dates, and formats are treated as distinct attributes.

Photography policy

Ouncebound uses real product reference photography with visible source attribution. A photograph is shown only when its depicted weight matches the catalog record. A same-weight series photo may be used when dates, portraits, finish, or minor production details differ, and that limitation is labeled.

If an exact-weight reference has not been verified, the record shows “Verified photo pending.” We do not substitute a one-ounce image for a ten-, kilo-, or hundred-ounce piece. Transparent cutouts remove distracting retail backgrounds without changing the product itself.

History and sources

History sections summarize identifiable programs, makers, designers, technical features, and relevant dates. Each record links to a principal source. Broad family histories can apply to several weights, but edition-specific statements are avoided unless the cited source supports them.

Rarity and XP

Rarity labels and XP are Ouncebound gameplay signals, not appraisals or market rankings. They combine broad availability, age, collector recognition, and the effort involved in discovering a record. They may change as the catalog improves.

Corrections

Cataloging physical bullion is iterative. If a weight, form, date, image, or history is wrong, email corrections@ouncebound.com with the record URL and a reliable source. We prioritize errors that could cause misidentification.
