Verifying Sellers of Sotheby's Art Auction Lots on 1stdibs

When purchasing a Sotheby's Art Auction Lot through 1stdibs, thorough seller verification is paramount. This guide will equip you with the knowledge to identify legitimate sellers and avoid potential fraudulent activities.

Understanding Potential Scams

Be aware of scams that specifically target high-value art transactions. These include: 'Off-Platform Negotiation Trap' where sellers try to move communication and payment outside of 1stdibs' secure system, and 'Stolen Gallery Credentials' where fraudsters impersonate reputable galleries.

Key Verification Steps

• ✓ Examine the seller's profile meticulously: Look for established history, positive reviews, and adherence to 1stdibs' policies.
• ✓ Request detailed provenance information: For Sotheby's lots, authenticity and ownership history are critical. Be wary of incomplete or suspicious provenance details.
• ✓ Cross-reference seller information: If the seller claims affiliation with a specific gallery or auction house, verify their legitimacy through independent searches.
• ✓ Utilize 1stdibs' messaging system: All communication should be conducted through the platform to maintain a record.
• ✓ Review high-resolution images and condition reports: Scrutinize the artwork for any signs of undisclosed restoration or damage.
• ✓ Consider professional authentication: For significant purchases, consider independent art authentication services.

What to Do If You Suspect Fraud

If you encounter any suspicious activity or believe a seller is not legitimate, do not proceed with the transaction. Report the seller immediately to 1stdibs customer support and contact Safe Trade Services for further guidance.
