The creation of an auction catalogue
A numismatic auction catalogue is much more than just a list of lots. It is a sales tool, a specialist text, a documentation of condition and a reference source all at once. In order for a catalogue to reach this level, it undergoes a clear production process at the auction house – from delivery to publication in print and online (often also via platforms such as Sixbid).
Delivery and preparation: The start of catalogue creation
The first step is to discuss the delivery and check whether the material is suitable for the planned auction. The auction house records the items internally, labels them clearly and ensures they are stored securely. At the same time, the contractual basis is established: commissions, fees, possible limits (reserves), insurance and billing arrangements. Information is already being gathered at this stage that will later enhance the auction catalogue – such as details of provenance, previous sales or literature.
Lot formation and catalogue structure: coins become saleable lots
Before the actual cataloguing process begins, a decision is made as to which items will be offered as individual lots and which as groups of lots. The structure is then created: chapters, order, placement of highlights. This structure is not just a ‘layout’; it directly influences user guidance in the online auction catalogue and thus bidder activity.
Numismatic cataloguing: identifying, documenting, describing
The core of cataloguing is identifying the items: type, denomination, mint, date and variants are determined and verified with references. Technical data such as weight and diameter are also included. Equally important is the description of the condition: minting quality, centring, surfaces, patina and any interventions such as cleaning or processing. Good catalogue texts are precise, transparent and yet formulated in such a way that collectors can quickly grasp what is on offer.
Authenticity check and legal review: security before publication
Authenticity and risk checks are carried out in parallel with the description. Depending on the area, style, stamp image, material effect and plausibility of the data are evaluated; additional expertise is consulted if necessary. In addition, legal and logistical aspects are examined, such as exportability and the correct presentation of conditions, fees and tax information.
Photography for the auction catalogue: images as a purchasing decision
A professional auction catalogue stands or falls on its images – especially online. That is why the auction house pays attention to realistic colour and surface reproduction, clean lighting and absolutely flawless assignment of images to lot numbers. For top lots, detailed photographs are added so that bidders can assess key features.
Estimation and auction: pricing with market comparison
Once the texts and images are ready, estimates and auction prices are determined. These are based on market observation, experience and comparative data: rarity, condition, provenance and current demand. Auction archives are often used for plausibility checks.
Practical relevance of Sixbid: Sixbid can be helpful in this context because it bundles auctions from many houses and provides historical lots and results as a basis for comparison.
Editing, layout and online catalogue: data is turned into a catalogue ready for publication
The technical work is followed by editorial production. Texts are standardised (house style, abbreviations, reference format), wording is refined and the media are created: print, PDF and web catalogue. Many auction houses also offer catalogues as PDF files, for example for previewing or marking lots.
Quality assurance before the auction: the final check is decisive
Before publication, a systematic final check is carried out: are the images, lot numbers, technical data and price information correct? Can any outliers in weight or diameter be explained? Are the auction conditions and fees consistent? This phase is crucial in order to avoid mistakes that could undermine trust or necessitate subsequent corrections.
Publication and reach: auction catalogue via Sixbid and other channels
Publication marks the start of outreach work. In addition to their own websites, auction houses use platforms to reach international bidders. Sixbid defines the Auction Catalogue as a directory of lots with images, descriptions, condition and estimate information – precisely the content that was previously produced in-house.
Depending on the auction, online or live bidding offers may also be integrated; Sixbid describes, among other things, a central login for multiple live auction access points.
After the auction: processing, results and long-term catalogue value
After the bid is accepted, invoicing, payment, shipping, export formalities and consignor settlement follow. However, the catalogue remains as a reference: it documents the offer, description and market response and is later used for market comparisons and provenance research. This is precisely why careful catalogue production is a long-term quality factor for an auction house.
Creating an auction catalogue means combining trust, expertise and sales
Creating an auction catalogue is a multi-stage process: consignment, lot formation, cataloguing, inspection, photography, pricing, editing, quality assurance and publication. Platforms such as Sixbid can play a role in market comparison and distribution – but the decisive value is created in the auction house: through professional precision, transparency and reliable production standards.
