Advising in the Collectibles Market: A Practitioner's Guide to Authentication, Grading, Reproduction Rights, and Platform Enforcement

By ·

This guide is for counsel advising a dealer, auction house, grader, platform, or collector. It begins with title rather than authenticity, because a thief passes no title and the market spends its diligence effort on the wrong question. It then covers what a collector actually owns, the reproduction position in listing and catalogue imagery, and the grading terms that are opinions rather than warranties. The middle steps map the licensing stack underneath trading cards and memorabilia, allocate consignment warranties, and locate publicity rights by domicile. The later steps address custom and altered items where rights holders do enforce, the platform processes that decide most outcomes in practice, and the intellectual property a professional seller owns and undervalues. It closes with the inventory that serves as insurance schedule, estate schedule, provenance file, and proof of ownership at once.
