Catalogue

The catalogue describes types, not individual items. One entry is a pattern — a particular year, metal and weight — shared by every piece ever struck. Here you check what a piece is; who holds it and at what price is found in the showcase and the market.

What a catalogue entry holds

• Attributes Metal, fineness, weight, diameter, thickness, mintage, mint, country of issue, face value — the factual layer, identical for every piece of that type.
• Description The history of the series, the origin of the motif, changes of design and what sets a given year apart from its neighbours.
• Gallery Images of the pattern — obverse, reverse, packaging, detail of the engraving.
• Collection Membership of a series, which takes you to the remaining years and formats of the same cycle.

Finding your way

• Start from the category. The category tree divides the catalogue by metal and kind of piece; search and filters work within the one you are in, together with its subcategories.
• Filter by attributes. Weight, metal and year narrow the list faster than a name — particularly in series issued year after year.
• Follow the series, not a single coin. From a catalogue entry you reach the whole cycle — from fractional formats up to the kilogram.

The catalogue and your collection

When you add a piece to your treasury, you point to a catalogue entry — that is how the system knows how much metal your item contains and how to price it. Shared data such as weight or fineness comes from the catalogue; whatever belongs to your copy alone — purchase price, condition, photographs — is recorded with it.
