How to sell Bullion at Catawiki’s online auctions?

When you submit your bullion items, this is your opportunity to get people interested in your lots and encourage them to bid. 

Submission Guidelines

Potential buyers are more likely to bid on lots with clear photos and with a good description stating all relevant information.

Lot Description

To help encourage potential buyers to bid on your lot, you should include a detailed description of your object(s). This should be thorough and honest, and follow the guidelines on the next section.


If you are using our website to upload your lots, tips will appear to give you guidance about what information we need to know about your lot. The fields that you fill in help to present the information in a way that’s easy for the buyer to read.

The required information includes:

  • Weight: in grams, ounces or kilograms
  • Material/metal: Gold, silver, platinum, platina or another metal
  • Fineness: .999, .925 or other fineness
  • Seal/certification: Sealed/certificate
  • Shape: Poured, minted, combibar, other
  • Dealer/refinery

Do you know any other interesting details about the history of the items? Let bidders know about them and share them in the description field.



Including high quality photographs is key to catching buyers’ eyes, ensuring they bid on your lot.

To allow our experts and buyers to get an accurate impression of an item, we require:

  • a minimum of three high quality photos with a neutral background, showing the obverse, reverse and side
  • clear visual of the refinery, weight, mint-marks, scratches, etc.


Image Guidelines

  • Please refrain from showing any prices, references to websites, phone numbers or addresses of stores in the photos.
  • Pay attention to the lighting. If you don’t have a professional lighting setup, consider taking a clean white sheet of paper to be used as a background and place it close to a window, in order to use daylight as the lighting source for your photos.
  • Use the macro option on your camera, be sure the item is in focus, and take the picture.
  • The more pictures the better, for instance of the edge of the item or some close-ups to highlight the quality of your item or of smaller details.
  • For lots with more than one bar or item, please have an overview image showing all the items in the lot, and then single pictures of all the items in the lot.

Tip: to avoid shadows appearing on the background, take a glass sheet, place it on the white paper background, and put the item on it.

Now that you know exactly what you need in order to create a fantastic lot, it’s time to start selling your bullion items. Start submitting your special objects for auction.

We look forward to receiving your lots soon - our experts can’t wait to see what you have to offer!
