Getting your submission ready

1. Fill in all the details and write a clear description

When you submit an object, you’ll see fields to guide you in providing the right information, such as: type of object, name of the athlete/team, size, condition, etc. These fields ensure your listing is clear, searchable, and easy for bidders to understand.

Note: To determine condition, we use the following grading system:

• New / as new – in the same condition as originally sold or obtained
• Very good – minor signs of use
• Good – typical wear or slight colour loss
• Fair – worn but intact, no loose embroidery or labels
• Poor – worn or faded with clear signs of damage (only accepted if rare)

Please also use the object description field to share:

• Unique features(including size, color and any other details) or notable history of the object
• What is included/not included (e.g. packaging, frame, etc.)
• Whether the object is signed or unsigned
• If the object is signed, the description should include the name of the signee(s), a description of where and when the signature was obtained, as well as a photo and video proof. If the signature was obtained through a third party, the description should include a clear description of the original source and, if possible, where and when the signature was obtained
• Presence of a certificate or letter of authenticity
• Where the object came from/how it was obtained
• If the object has any flaws it should be described in a detailed way and shown through photos

Tip: The more detail you provide, the easier it is for bidders to understand the value of your object – and the more likely it is to sell. Find here more tips on how to write a clear, accurate description. 

📌 Examples of a well-written description:

“This lot includes a red left boxing glove in size OZ18 from the brand Everlast.

The item is signed by Mike Tyson with a silver permanent marker.

Both the glove and the signature are in perfect condition.

The signature was personally applied by Mike Tyson during a commercial signing session in January 2025 in Las Vegas, USA.

The glove is presented in a plexiglass display case, which is included with the glove. This display case measures 25 x 30 x 30 cm”.

2. Great photos matter

Photos are the first thing bidders see – so make them count! We recommend including at least 5 high-quality images that clearly show the condition and details of your object. This helps bidders make informed decisions and increases your chances of a successful sale.\
